PHOENIX (AP) - Authorities say the gun used by a Phoenix teenager to fatally shoot his ex-girlfriend and then himself belonged to his older brother.
Phoenix police announced Tuesday that the gun was legally possessed and was kept in a locked bedroom.
They say it appears that the 15-year-old boy broke an outside window, stole the gun and got a ride from a friend to a north Phoenix home last Friday.
Police investigators say 16-year-old Anastasia “Ana” Greer was at the home of a friend and was running when she was shot.
Witnesses told police that they saw Matthew Bolton chase Greer and heard the fired shots in what authorities are calling a murder-suicide.
Police say it’s still unclear what set Bolton off. Both teens were students at Sandra Day O’Connor High School.
