A shooting at a suburban Phoenix high school that killed two 15-year-old girls and caused panic among parents was a murder-suicide, police say.
Police revealed that a suicide note was found at the shooting scene at Independence High School in Glendale. They said each girl was shot once, and a weapon was found near the bodies.
Authorities say a male classmate provided the handgun used in the murder-suicide. Police say one of the girls told the 15-year-old boy she needed it for protection. Authorities are reviewing his involvement in the matter.
