Suspect Arrested in Killings of 5

A man was arrested in the San Francisco Monday and booked on murder counts in the investigation of five brutal slayings that police at first thought included a murder-suicide. “This was a complex crime scene,” city Police Chief Greg Suhr said. “We didn’t know what we had.” The 35-year-old suspect, Binh Thai Luc, was taken in by police Sunday. While the exact cause of death in the murders has not yet been determined, police said 40 investigators are working on the case, which began after a woman found the five bodies in a house Friday.
