A 35-year-old man was arrested Sunday in the gruesome killing of five people in a San Francisco home, police said.

Binh Thai Luc, a San Francisco resident, 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 southern part of the city. Police said the crime scene was so tangled that police couldn't determine the cause of deaths.

"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.

He declined to release details of the arrest or what led investigators to Luc.

He also did not say whether investigators have determined a motive for the killings, saying only that Luc knew the victims and that an "edged weapon" was involved in the slayings.
