Police arrest Long Beach man suspected of murdering, assaulting girlfriend

Police on Tuesday morning found a 37-year-old woman dead in a home near Atlantic Avenue and 10th Street after they received a call about unknown trouble, officials said.

When they arrived at 7:30 a.m., they found the woman with what appeared to be blunt force trauma to the upper body and responding paramedics determined she was dead at the scene, police said.

“The preliminary investigation indicated the victim was physically assaulted by her cohabitant boyfriend, who remained at the scene and was taken into custody by responding officers,” police said in a news release.

The victim was identified as Sena Khim from Long Beach.

The suspect, 59-year-old Long Beach resident Soeun Sam, was booked on suspicion of murder and is being held at Long Beach City Jail on a $2 million bail.

Police do not yet know the motive for the assault and are still investigating. They ask anyone with information to contact homicide detectives Oscar Valenzuela or Sean Magee at 562-570-7244.
