ALAMO, Calif. – BJ Byrd, a physical education teacher at Rancho Romero Elementary School who is a lesbian, says she was the target of graffiti vandals.

Byrd told authorities that she found the anti-gay graffiti written in pencil or pen on an equipment shed on campus on Jan. 3, and she spoke about the vandalism at a meeting of the school board this week.

The graffiti specifically named her and contained an anti-gay slur, description of a sexual act and an expletive.

The Contra Costa Sheriff’s Department says the vandalism is a hate crime but has not identified any suspects.
