GLENDALE, Ariz. (AP) – A student says she was shocked to learn that two teens died in a shooting at her suburban Phoenix high school.

Lanie Walter, a senior, said Friday that the shooting was heartbreaking because “everyone is so loving” at Independence High School.

She says she heard ambulances on her way to the campus in Glendale but didn’t think much of it until her first class went on lockdown.

She called her parents to tell them she was OK and said her mother was relieved because she had been watching the news.

Police say two 15-year-old girls, both students, were found dead on campus. Authorities didn’t know what led to the shooting but say they’re not looking for anybody else.
