Results of examination:<\/p>\n
This report supplements and confirms the preliminary report furnished your office on December 12, 1978.<\/p>\n
Specimen Q1 consists of four pieces of lead shot which have been determined to be size “F”. This size of shot is not commercially loaded into shot shells in either the United States or Great Britain. However, size “F” shot is available in many countries for hand or reloading purposes.<\/p>\n
[Page 5]<\/p>\n
Specimen Q2 is a .38 Special or a .357 Magnum bullet jacket which has been fired from a barrel rifled with six grooves, right twist, such as the K5 revolver. However, the barrel of specimen K5 was found to contain a large quantity of foreign material and corrosion which affected the microscopic markings used in identification. Therefore, it was not possible to determine if Q2 had been fired from K5. None of the other recovered weapons could have fired Q2.<\/p>\n
Specimen Q3 was identified as having been fired from the K15 rifle.<\/p>\n
Specimens Q4, Q6 and Q20 are lead cores from jacketed bullets which do not contain any marks of value for identification purposes. Therefore, the origin of Q4, Q6 and Q20 could not be determined.<\/p>\n
Specimens Q5 and Q18 are .30 caliber bullet jackets which were fired from a barrel(s) rifled with four grooves, right twist such as the barrels in the K17 and K20 rifles. However, due to a lack of sufficient matching microscopic marks between Q5, Q18 and test bullets fired from K17 and K20, it was not possible to determine if Q5 or Q18 had been fired from K17 or K20.<\/p>\n
Specimen Q7 os a .380 Auto caliber jacketed bullet which was fired from a barrel rifle with six grooves, right twist. Although the barrel of the K11 pistol contained six grooves, right twist, nothing was found to indicate that Q7 had been fired from K11.<\/p>\n
Specimens Q8 and Q19 are .30 caliber bullet jackets which were fired from a barrel(s) rifled with six grooves, right twist such as the barrels in the K14 and K15 rifles. However, there are not sufficient microscopic marks of value for identification purposes in either Q8 or Q19. Therefore, it was not possible to determine if they had been fired from K14 or K15.<\/p>\n
The Q9 and Q10 bullets were identified as having been fired from the K3 revolver.<\/p>\n
[Page 6]<\/p>\n
The Q11 through Q15 cartridge cases were identified as having been fired in the same firearm; however, they were not fired in specimen K11.<\/p>\n
Specimen Q16 was not fired in any of the recovered .308 Winchester caliber firearms.<\/p>\n
Specimen Q17 was identified as having been fired in the K15 rifle.<\/p>\n
Specimen Q21 does not contain sufficient microscopic marks of value for identification purposes. Therefore, it was not possible to determine if Q21 had been fired in K19 or K17. Specimen Q21 was not fired in K16.<\/p>\n
Specimen Q22 does not contain sufficient microscopic marks of value for identification purposes. Therefore, it was not possible to determine if Q22 was fired in K17. Specimen Q22 was not fired in K16 or K19.<\/p>\n
The Q23 through Q27 cartridge cases were identified as having been fired by the K23 rifle.<\/p>\n
Specimens Q28 and Q29 are consistent with 16-gauge shot shell wads but could not be identified further.<\/p>\n
