Teen Charged in Teacher's Slaying Accused in New Attack

The 15-year-old Massachusetts boy accused of raping and murdering his math teacher last year allegedly attacked a female staffer at his youth-detention facility, police say. The woman is apparently OK and declined medical treatment at the scene, while Philip Chism has been taken to a hospital for an evaluation, reports the Boston Globe. Authorities aren't saying exactly what happened, but WCVB-TV reports that Chism can be seen on surveillance video carrying what appears to be a pencil and following the woman into a locker room.

After he began choking the woman, other staffers quickly pulled him away, reports the TV station, which points out that the scenario "bears a chilling resemblance" to how teacher Colleen Ritzer was murdered at Danvers High School last year. Chism is accused of following her into a school bathroom and killing her. He has pleaded not guilty in that case and is still awaiting trial.
