Binh Thai Luc Arrested in Connection with the brutal killing of five in San Francisco home

A San Francisco man was arrested today on suspicion of killing five people in a home, leaving a gruesome crime scene that has investigators struggling to identify the victims and determine the causes of death.

Binh Thai Luc, 35, was taken into custody Sunday morning and booked on five counts of murder, police Chief Greg Suhr said.

The bodies of the three women and two men were found early Friday by a woman with access to the home in the Ingleside District in the southern part of the city.

The crime scene was so tangled that police couldn't initially determine whether they were dealing with a murder-suicide, or whether a suspect was at large. They also initially thought that at least two of the victims were shot.

'This was a complex crime scene. We had five deceased persons apparently from blunt force trauma. We didn't know what we had,' Suhr said.

The victims still have not been identified and police have not been able to determine the exact causes of death or offer a motive for the slayings.

Suhr said 40 investigators were working on the case.

The chief declined to say what led investigators to Luc, saying only that the suspect knew the victims and that an 'edged weapon' was involved in the slayings.

He said Luc had a prior criminal record, but did not elaborate. Read More
