Ballistic examination of two empty cartridges recovered from a scene where businessman Jacob Juma was murdered match with a gun found on four suspects who were killed over the weekend. Police say they found the AK47 rifle on four suspects killed near Nyayo Stadium in Nairobi on Saturday night. A pistol was also recovered during the incident. Inspector General of police Joseph Boinnet says the new development could therefore lead to the arrest of the murderers. “The areas covered in investigations include ballistic examination of two spent cartridges recovered from the scene which show it was from an AK47. Examination of two similar weapons recovered during recent encounters with criminals indicates one of them could be the murder weapon. This could therefore lead to the arrest of the murderers of the late Jacob Juma,” said Boinnet.
