After discovering the body of 16-year-old Andy Zeng early Sunday morning in response to a suicide call, San Francisco police arrested a teen for murder. "Authorities found Zeng, of San Francisco, deceased in a home in the 2100 block of Queseda Avenue, just south of Interstate Highway 280, at around 4:30 a.m. Cops were called to the home after someone reported a suicide," reports The Examiner. Although police "suspect foul play," as well as the involvement of other suspects, they have yet to name a motive. [Ex]
