A woman’s body washed up on a Peninsula beach this week. Her cause of death wasn’t immediately apparent, but homicide detectives do not suspect foul play, Long Beach police said.

At about 1:45 p.m. on Wednesday, someone called 911 to report seeing a body that “appeared to have washed ashore” near 61st Place off East Ocean Boulevard, according to Long Beach police.

When officers arrived, they found a woman’s body “on the shoreline,” police said.

Homicide detectives responded but soon turned the scene over to the Los Angeles County Medical Examiner’s Office, which examined the woman’s body but wasn’t immediately able to determine what killed her. A spokesperson said further tests are scheduled, but results can sometimes take months.

Authorities identified her as 40-year-old Mariah Miller. She was homeless, they said.
