(CBS/AP) SAN FRANCISCO - The San Francisco District Attorney says he is "unlikely" to seek the death penalty against a man suspected of killing five people in a San Francisco home last week.

San Francisco prosecutors say Binh Thai Luc will be charged with five counts of murder with special circumstances that could make him eligible for the death penalty. His arraignment is scheduled for Wednesday afternoon.

District Attorney George Gascon told CBS San Francisco Tusday that he would "thoroughly review the details of the case, but it is unlikely I will seek the death penalty."

The Vietnam native was arrested Sunday after five bodies were found Friday in what police initially thought was a murder-suicide. The victims include a married couple, their adult children and the son's girlfriend.

Authorities have not yet determined a motive for the killings.

Officials say an immigration judge ordered Luc's deportation six years ago after he served time for armed robbery and assault. But he was never deported because the Vietnamese government didn't provide the necessary paperwork.
