SAN FRANCISCO (KGO) — A 17-year-old accused of shooting San Francisco 49ers wide receiver Ricky Pearsall brought a gun to school the week before the attack.

A Tracy police report details an incident that occurred on August 21 at Stein High School, an alternative school for troubled students.

The student’s name and personal information have been removed from the report because he is a teenager.

The teenager is accused of shooting Pearsall in the chest during a robbery attempt on August 31 in Union Square.
