SAN DIEGO (AP) – San Diego police say a 15-year-old boy left a suicide note before he was killed by officers after pointing a BB gun at them in a high school parking lot in the dark.

Assistant Police Chief Brian Ahearn told The Associated Press on Monday that police found the note on the Torrey Pines High School student and believe he called police and pointed the BB gun at them so he would be shot.
