This booking photo provided by the San Francisco Police Dept. shows Binh Thai Luc, 35, who was arrested Sunday, March 25 2012 and is being held on suspicion of five counts of murder. Luc was taken into custody in the murders of five people inside a San Francisco home Friday, in a surprise twist after police initially hinted that it was a murder-suicide case. Investigators are sorting through a crime scene that they say is so complicated that they still can't identify all the victims three days after the gruesome killings.
