S.A. 12-031 <br />Investigator: BRETT ANDERSEN Approved By: <br />Date of Report: 04/02/2013 Date: 04/02/2013 <br />Page 19 of 20 <br />without malfunction. The 3 fired cartridge casings from the scene (EM-1 and EM-2) were <br />determined to have been fired by GARCIA’s Glock model 22 pistol. <br />The bullet from the scene (EM-4) and the bullet recovered from LEON’s back both <br />shared class characteristics with the Glock pistol, however it could not be determined if the <br />bullet or jacket were fired from GARCIA’s pistol. The result of the microscopic comparison of <br />the bullet was inconclusive. The jacket lacked marks suitable for microscopic comparison. <br />GUNSHOT DISTANCE ESTIMATION <br />Evidence items EM3 and EM5 were examined for the presence of bullet holes, <br />gunpowder particles and gunpowder patterns. One hole was located near the center of the <br />shirt, in the design side of the larger shirt piece. One imbedded particle was observed near the <br />hole. The area around the hole tested positive with a presumptive test for lead. <br />Eight cartridges from one of the fully loaded Glock magazines were used to generate <br />gunpowder pattern exemplars from the pistol at muzzle to target distances of 6, 12, 18, 24, 30, <br />36, 48, and 60 inches. <br />Assuming the material of the shirt and the gunpowder pattern targets behave similarly, <br />and significant amounts of gunpowder were not lost during the prior handling of the shirt, the <br />shot into the shirt by the Glock pistol was at a muzzle distance between 24 and 36 inches. <br />BACKGROUND INFORMATION <br />LEON has a California . He has previously been <br />arrested for the following charges: <br /> <br />
