A Grays Harbor woman, 21, and her boyfriend are in custody for investigation of the death of her newborn baby in Ocean Shores.
An autopsy Sunday found the baby died of skull fractures and brain injuries. Deputy Coroner Lane Youmans said the death was a homicide.
The body was found in an empty lot Friday evening by a woman walking her dog.
Tips led police to the mother and her boyfriend at the Oasis Motel in Ocean Shores, where they believe the baby was born. Both were booked into the Grays Harbor County Jail.
