September 12, 14 and 20 and November 8, 2006, April 3, 2008, August 9, 2011, and March 26 and May 31, 2014, the assistant prosecutor received the information related to his request.100 74. In addition, on June 5 and July 5, 2006, the section prosecutor asked the chiefs of Precincts 11, 14 and 16 of the National Civil Police, for information on the number of weapons seized and on the weapons used to commit crimes between August 12, 2005, and July 4, 2006, within the district covered by each Precinct.101 Also, on September 11 and 12, 2006, the assistant prosecutor asked the head of the Department for the Control of Weapons and Ammunition to advise whether Precincts 14 and 16 had remitted weapons to him, specifically 9 mm caliber firearms.102 In response, on September 14 and 20, 2006, the Department sent the list of 9 mm caliber firearms that it had received from Precincts 14 and 16.103 75. Furthermore, there is evidence that, following a request by the assistant prosecutor, ballistic analyses was performed on June 30, August 18 and October 5, 2006, comparing different ballistic fingerprints with the bullet and casing collected at the crime scene, all with negative results.104 Meanwhile, on August 20, 2008, and January 31, 2011, ballistic tests were conducted to identify various firearms and the caliber of different cartridges, casings and bullets was established.105 76. On November 7, 2006, the Department for the Control of Weapons and Ammunition of the Ministry of National Defense remitted eight firearms with their respective magazines, cartridges and casings to the Ballistics Laboratory of the Technical and Scientific Department of the Public Prosecution Service106 and, on September 16, 2008, these were forwarded to the INACIF Central Evidence Storage Unit.107 Subsequently, the assistant prosecutor asked the INACIF Criminalistics Laboratories Unit to advise whether, the database of the Integrated Ballistics Identification System (hereinafter “IBIS System”) contained the ballistic fingerprints of the firearms registered with the General Directorate for the Control of Weapons and Ammunition (DIGECAM), and to determine whether the said eight firearms were included in the IBIS System records. On October 25, 2011, the Criminalistics Laboratories Unit advised that it had no record of the ballistic fingerprints of the firearms registered in the DIGECAM and that, at that time, it was not possible to respond to the request owing to the material impossibility of entering into the IBIS system cases that occurred before December 7, 2010, the first date on which data was introduced into the system. 108 Lastly, and following a request from the assistant prosecutor, there is evidence that, at least by November 15, 2012, the INACIF had entered the casing and the bullet collected into the IBIS System, without these corresponding to any other items entered into the system at that time.109 Cf.
