NATASHA Derby was killed by a "home-made" bullet, a firearms expert revealed at her murder trial this week.
Michael Vaughan, a gun specialist, said he believed the bullet was "home made" as it was an "improvised" metallic object for a modified cartridge case.
The expert, with 13 years experience, also ruled out Natasha having been hit by the bullet after a ricochet. There was "no evidence" to back this theory as the wound to Natasha was circular.
