gunshot residue cases

SEM/EDS analysis has existed for a long time and been used in GSR analysis since the 1970s. A positive GSR finding is most probative in cases where a suspect denies proximity to a discharged firearm because GSR is not common to the average person’s daily environment. at 312, 901 A.2d 208 (quoting United States v. Myers, 550 F.2d 1036, 1049, 1050 (5th Cir.1977)) (internal citations and quotation marks omitted). Id. Forensic Ballistics in Court: Interpretation and Presentation of Firearms Evidence is an accessible introduction to firearms and ballistics evidence and how this is analysed and presented as evidence in a court of law. Prior to trial, the circuit court dismissed the drug charges against Thompson, and excluded all evidence of the drugs from trial. A single particle of … Found insideThis handbook will serve as a useful reference not only to assist military and contractor personnel within the various combat locations but will also prove to be beneficial for law-enforcement, crime laboratory personnel, forensic firearm ... Tamper-evident, pre-sealed Kit Envelope, 6" x 9" 1 ea. The areas of the garment for sampling depend on whether the person wearing the clothes was believed to be firing a gun, carrying one in a specific location, or trying to conceal a gun in a particular manner. But gunshot residue also found on his new girlfriend Maria Korotaeva, 22 The discovery throws confusion over the previously 'open and shut' case By Gerard Couzens for MailOnline While most books on firearms focus solely on the physical aspects of firearms, this book addresses forensic issues relating to the chemical aspects of firearms and ammunition. Additionally, no armed personnel or persons who made contact with the firearms section on the day of analysis should have access to those areas. MAIP worked with John Kilty, who headed the FBI’s gunshot residue analysis unit from 1975 until 1987. Upon forensic examination, the gun recovered by Drewer could not be excluded as the weapon that fired some of the bullets that were recovered from the crime scene at 923 East Church Street.

Step-by-step Kit Instruction Sheet; 1 ea. The objective was to determine if the pistol deposited gunshot residue (GSR) on the shooter’s hand. Gunshot residue is material deposited on any part of the body, most particularly the hands, face, and clothing of the shooter, as a result of the discharge of a firearm. 2781, 61 L.Ed.2d 560 (1979)); accord Smith v. State, 415 Md. Our criminal defense law firm frequently defends gun cases which are charged under Pennsylvania’s Uniform Firearm Act as violations of that Act (aka VUFA offense). The text also reviews basic firearm design, function, ammunition components, and the terminology required for understanding evidence encountered at the scene. Once the right to counsel attaches, a criminal defendant is entitled to the presence of counsel at every “critical stage” of his trial. While law enforcement personnel could be a potential source of GSR because they carry guns, studies have shown that few of them have particles on their hands because they clean their hands much more often than they touch their weapons.14 Nevertheless, police officers should avoid contact with a subject’s hands before sampling. The jury was directed that, if they found evidence of flight, they must then decide if that evidence demonstrated a consciousness of guilt. The difficulty lies in the fact that while analysts can report that the particles came from a fired weapon, they cannot describe how they were deposited on the item. Gunshot Residue Examination 1. Leadership Spotlight: I Should Have Eaten More Ice Cream! After reading the case and guidelines thoroughly, reader should go forward and start the analyses of the case. See Johnson, 445 F.3d at 795 (“Incident to a lawful arrest, ‘it is entirely reasonable for the arresting officer to search for and seize any evidence on the arrestee's person in order to prevent its concealment or destruction .”). When Hitty finished swabbing appellant's hands, he left the holding cell without engaging in any additional conversation with appellant. UK Gun Expert, Gunshot Residue Expert, Ballistics Expert e: info@forensicscientific.com t :+44 (0)1953 882242 As to the timing of the GSR test, Hitty testified that within 45 minutes after appellant's arrest, he approached appellant in the booking area of the Salisbury Police Department. Id. 10. Drewer was in the area of Priscilla Street when he heard the radio communications from Mitchell and Robinson regarding the fleeing assailant. Sorrell v. State, 315 Md. Alternately, we note that Hitty's testimony established that there were temporal and practical barriers that greatly decreased the feasibility of waiting to obtain a search warrant prior to collecting the GSR evidence from appellant's hands. So, the question arises, “Why analyze for GSR?” First, the technology behind the analysis of gunshot residue is unquestionably scientifically sound. Leadership Spotlight: The Leader Knows Best? The State responds that appellant failed to properly preserve his arguments regarding self-incrimination and deprivation of his right to counsel for appellate review, and that even if they were preserved, appellant's arguments on these points are without merit. Id. Analysts also can use clear adhesive lifters; however, these require an extra step of carbon coating to prevent charging from the electron beam hitting the sample during analysis. In our view, Thompson is distinguishable. Subsequently, forensic laboratories started applying this technology to case work. Nevertheless, GSR findings continue to add value simply because numerous population studies have shown that GSR is not normally found on the average person.3 In addition, exhaustive study into the search for false positive results has strengthened the opinion that SEM/ EDS particle analysis can attribute the source of certain particles to the discharge of a firearm. Gunshot residue has been known to be one of the most common and most scrutinized sources of evidence that is examined in violent crime investigations. At least 140 SEMs used for GSR analysis exist in crime laboratories throughout the world.16 Usually, such facilities use a sophisticated software program to automatically search adhesive stubs for GRS particles. Gunshot Residue Production and Analysis. Thompson, 393 Md. The State, of course, contends otherwise. ��(�� Case Western Reserve University School of Law Scholarly Commons Faculty Publications 1991 Gunshot Residue Tests Paul C. Giannelli Case Western University School of Law, paul.giannelli@case.edu 2. The police observed Pettiford only minutes after the shooting, in a location only a few blocks from where the incident had occurred, traveling in the direction the shooter reportedly was driving when he left the scene of the crime. In cases in which a handgun was used, gunshot residue was found in 90 percent of the cases. We now consider appellant's argument that the warrantless seizure of the GSR evidence constituted an illegal search, requiring that the evidence must be excluded. Leadership Spotlight: Should You Always Lead from the Front? 291, 302, 901 A.2d 208 (2006)(quoting Ware v. State, 348 Md. 7. Documents in the case were disclosed by the prosecution that had not been turned over to Burgess’s trial lawyer. Belote v. State, 411 Md. Most primers used in North America consist of lead styphnate (Pb) as an initiating explosive, barium nitrate (Ba) as an oxidizer, and antimony sulfide (Sb) as a fuel; therefore, a combination of these elements in a single particle proves very significant. Tests show that people standing within 3 feet to the side of a shooter may have GSR on their hands, whereas those standing 10 or more feet in the same direction typically will not.6 This can vary with the type of gun and ammunition, number of shots fired, and the environment of the shooting. The testimony of the various witnesses, as we have reviewed, constituted more than “some evidence” that appellant fled on the night he was arrested. 595–610, 1976. § 5–133(c), defining the penalties for a violation of § 5–133(b), specifies that “[a] person may not possess a regulated firearm if the person was previously convicted of ․ a crime of violence; ․ a violation of [enumerated sections] of the Criminal Law Article;” or an offense in another State that would constitute one of the specified disqualifying offenses if it had been committed in Maryland. We review the trial court's decision to provide a requested jury instruction under an abuse of discretion standard. 1 A.R. 0000000476 00000 n A particle must meet certain criteria to become characterized as GSR. By. This book will be of value to practicing forensic scientists (firearm and toolmark examiners), ballistics experts, crime scene personnel, police departments, forensic consultants (generalists), attorneys and judges, medical examiners ... 3 (July 2006); P.

Knowing this distance, vital questions regarding the re-construction of the crime scene can be known. Often, the original firearm used in commission of a suspected crime is not available for testing or is damaged. Found insideThis book is published as part of the AAFS series 'Forensic Science in Focus'. Further, technology has made GSR analysis quicker and easier. Second, the morphology of the tiny condensed primer residue particles typically is spheroid or shows shape characteristics of having been molten.18. Chemical Analysis of Firearms, Ammunition, and Gunshot Residue, Second Edition continues in the tradition of the popular first edition, filling the void in forensic texts on the subject. “Automated SEM/EDS Analysis of Airbag Residue II: Airbag Residue as a Source of Percussion Primer Residue Particles,” Journal of Forensic Sciences 54, no. at 795 (quoting Chimel v. California, 395 U.S. 752, 763, 89 S.Ct. The firing pin of a gun hits the back of the cartridge, activating the shock-sensitive primer, which ignites the gunpowder, forcing the bullet down the barrel of the gun and on its path. Primer consists of a ratio of multiple chemicals such as lead styphnate, barium nitrate, and antimony sulfide. Indeed, twice during his closing statement, defense counsel made exactly that argument, proffering to the jury appellant's alternative reason for fleeing from the police. Fields was found a few moments after the shooting by Corporal Brian Whitman of the Salisbury Police Department. The circuit court sentenced appellant to life imprisonment on the charge of attempted first degree murder. He was pursued by Mitchell, and two other officers, and was eventually apprehended and placed under arrest. Jomel Fields also testified that the gun identified as State's Exhibit 1 “looked like” the gun that was used to shoot her. Each facility must assess the needs of the community it serves, the importance of the testing, and the cost of analysis. In cases where the firearm is discharged from a close range, the visual examination may reveal burning, blackening, tattooing, etc. On this basis, the Court concluded that the warrantless search did not violate the defendant's Fourth and Fourteenth Amendment rights, and therefore, the results of scientific tests performed on the evidence collected from Cupp's hands was properly admitted at his trial. at 795–96. Based upon the recently developed glue-lift collection of gunshot residue particles for examination in the scanning electron microscope with energy dispersive X-rays, this laboratory has undertaken a research program to determine if reconstruction of gunshot deaths is feasible. Gunshot residue (GSR) is particles that originate from partially reacted components of explosive primer and propellant as well as the bullet, cartridge case, and the firearm. �#b�0�a���٠Ơ� �����lƐ�3�!ԁh,{�R�sEb� ��OefACI���� ��������N�ii�\xX00=[���2@� �sd� 291, 901 A.2d 208 (2006). 2638, 110 L.Ed.2d 528 (1990); United States v. Dionisio, 410 U.S. 1, 7, 93 S.Ct. The often repeated test for sufficiency of the evidence is, “ ‘whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.’ “ Bordley v. State, 205 Md.App. So, gunshot residue experts and testimony on this subject matter where you have a gun case where people are alleged to have been using or firing weapons is real important stuff and you have to get in front of a good criminal defense attorney immediately. Gunshot Residue Analysis Information Form The trial court did not abuse its discretion by providing the flight instruction. Rates of loss vary widely with the activity of the subject. 8. Id. “The flight doctrine has been applied to a broad spectrum of behavior occurring after the commission of a crime: ‘flight from the scene or from one's usual haunts after the crime, assuming a false name, shaving off a beard, resisting arrest, attempting to bribe arresting officers, forfeiture of bond by failure to appear, escapes or attempted escapes from confinement, and attempts of the accused to take his own life.’ “. Considering all the circumstances, we agree with the suppression court's determination that exigent circumstances justified the limited invasion of appellant's privacy to collect the GSR evidence from his hands without delaying to obtain a warrant. Yes, it can be washed off. Per Wikipedia, GSR is the consistency of flour and typically only stays on the hands of a living person for 4–6 hours. Wiping the hands on anything, even putting them in and out of pockets can transfer GSR off the hands. Victims don't always get GSR on them; even suicide victims can test negative for GSR. 1 (March 2001).11 Chavez and Crowe.12 Trimpe and Wright.13 Roger Aaron, “Gunshot Primer Residue: The Invisible Clue,” FBI Law Enforcement Bulletin, June 1991, 19-22.14 McCullough and Niewoehner; and D. Gialamas et al., “Officers, Their Weapons, and Their Hands: An Empirical Study of GSR on the Hands of Nonshooting Police Officers,” Journal of Forensic Sciences 40, no. Pettiford initially attempted to evade the police, but was quickly apprehended. Torre, “Source of Non-GSR Particles Containing Lead, Barium, and Antimony,” Journal of Forensic Sciences 47 (2002): 494-504; Michael Trimpe and Diana Wright, “Summary of the FBI Laboratory’s Gunshot Residue Symposium, May 31-June 3, 2005,” Forensic Science Communications 8, no. The court further noted that it would be unnecessarily burdensome for the police to have to closely monitor an arrestee to ensure that the evidence was not destroyed while they obtained a search warrant to collect the samples. 386, 401, 813 A.2d 231 (2002) (stating that reviewing court makes “an independent, de novo, constitutional appraisal by applying the law to the facts presented in a particular case”); Nathan v. State, 370 Md. The decision in Pettiford, permitting the admission of GSR evidence collected without a warrant pursuant to a detention or arrest supported by probable cause, is consistent with determinations rendered by other Federal Courts. 0 This text offers an innovative approach to learning about crime scene investigation, taking the reader from the first response on the crime scene to documenting crime scene evidence and preparing evidence for courtroom presentation. During the collection of the GSR sample, appellant indicated that “he wanted to make no statements without a lawyer present.” Appellant also questioned whether Hitty had a warrant to conduct the GSR test. On November 5, 2010, at about 7:00 p.m., Jomel Fields was sitting in her car, parked in the driveway of a residence at 923 East Church Street in Salisbury, Wicomico County. Upon examination at Peninsula Regional Medical Center, Fields was found to have suffered eleven bullet wounds in her lower abdomen, lower back, pubic area, right thigh, and left leg. Program, Leadership Spotlight: Helium vs. At that time, Fields saw a police car on the adjoining block and hit her panic alarm. Therefore, his rights under the protections afforded by the Fifth Amendment or Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. “In reviewing the ruling on a motion to suppress evidence, we consider only the evidence contained in the record of the suppression hearing.” Bost v. State, 406 Md.

Most residue originating from the barrel of a gun is This volume will serve both as a textbook for forensic programs, and as an excellent reference for forensic practitioners and crime scene technicians with science backgrounds. See, e.g., State v. Odom, 303 N.C. 163, 277 S.E.2d 352, 355 (N.C.1981) (concluding that arrestee was not entitled to counsel during GSR test, relying on Supreme Court cases indicating that the collection of physical evidence, such as fingerprints, blood, clothing, and hair, does not constitute a critical stage of trial); United States v. Love, 482 F.2d 213, 217 (5th Cir.1973) (holding that collection of physical evidence was not a critical stage during which arrestee was entitled to counsel because such tests “involve[ ] none of the probing into an individuals' private life and thoughts that marks an interrogation or search.”). 2034, 23 L.Ed.2d 685 (1969)). ]”9 Id. This review paper covers advances in scientific methods applied to Gunshot Residues reported since the 16th Interpol Forensic Science Symposium in October 2013. An expert assumes the role of teacher when describing gunshot residue and its analysis. Cupp submitted voluntarily to an interview at the police station, at which time the officers observed a dark spot on Cupp's finger that appeared to be blood. The examination area and the SEM instrument area should be located far from the firearms section of a laboratory. The samples from Cupp's hands were later analyzed and found to contain traces of his wife's skin and blood cells and fabric from her nightgown. Gunshot residue - GSR. An expert in forensic science testified Friday that Jose Ines Garcia Zarate has exactly one particle of gunshot residue on his hands – enough for the prosecution to claim as evidence that he fired a pistol, but little enough to give the defense grounds to argue that it was inconclusive. § 5–101(p)(1), that “any firearm with a barrel less than 16 inches in length” is a handgun, and that “any handgun is a regulated firearm.” The jury was also given an opportunity to examine the gun, and thus were able to determine for themselves that it met the definition of a regulated handgun. McNiel suggested that she attempt to retrieve the police file of the case to determine if a gunshot residue test had ever been conducted on Jennings’s robe. But, “[w]e make our own independent appraisal as to whether a constitutional right has been violated by reviewing the law and applying it to the facts of the case.” Bost, 406 Md. When the assailant continued to run, Drewer exited his vehicle and continued the pursuit on foot. The Court noted that incident to an arrest supported by probable cause, police are permitted to conduct a warrantless search of the items or area within the immediate control of a detained suspect for the purpose of seizing any weapons or incriminating evidence that might otherwise be used or destroyed. The Missouri Attorney General’s Office announced on Thursday that they have charged 65-year-old Alice Weiss with second-degree murder for the death of James Summers in 2004. at 356, 812 A.2d 1050) (emphasis in original). Drewer pursued the gunman with his emergency equipment activated, repeatedly yelling over his vehicle's intercom for the man to stop. To preserve an assignment of error based on an evidentiary question, a party is required to bring its position to the attention of the trial court so that the court may pass upon any objection, and possibly correct any errors. While questioning Pettiford, the police observed bullet holes in the driver's side door of his car. JUDGMENTS OF THE CIRCUIT COURT FOR WICOMICO COUNTY AFFIRMED. Instead, appellant asserts, one could reasonably infer that he fled from the police because he did not want to be apprehended while carrying a regulated firearm. We find that this fact, which was known to all parties involved although not revealed to the jury, undermines the confidence by which the inference could be drawn that Mr. Thompson's flight was motivated by a consciousness of guilt with respect to the crimes for which he was on trial in the present case; it provides a foundation for the alternate, and equally reasonable, inference that Mr. Thompson fled due to the cocaine in his possession, an action a person in his position may have taken irrespective of whether he also shot and attempted to rob Mr. Gottesman. Appellant was also found to have gunshot residue on his hands following his arrest. If gunshot residue matching is to be attempted in a case, it will behoove an investigator not only to obtain a gunshot residue sample from the bore of the weapon, but also from the breech components. The Court next noted testimony indicating that GSR evidence remains detectable on a person's hands for only a limited period of time after a shooting, and that it is easily destroyed. Fields was unable to provide a detailed description because her attackers had held their guns to her temple, preventing her from turning her head.
