SAN ANTONIO (AP) — Authorities say a woman faces gun and drug charges after shots were fired into a San Antonio educator's parked car in an apparent dress code dispute.

Grace Seward has been charged with deadly conduct, unlawfully carrying a weapon in a gun-free zone and possession of marijuana. The Bexar (bayr) County Sheriff's Office on Friday said officers found marijuana on the 22-year-old Seward during booking.

Wagner High School, in the Judson Independent School District, was on lockdown part of Thursday after reports of gunfire. Nobody was hurt.

Sheriff's spokesman James Keith says a student, apparently someone Seward knows, was disciplined for an unspecified dress code violation. The principal's car was later struck with a bat and shot three times.

Online jail records Friday didn't list bond or attorney information for Seward.
