"There was no clothing on her and her body was laying on the pavement, but we don't know how she ended up on the pavement, if she jumped out or if she was thrown out," said Los Angeles County Sheriff's Department Sgt. Sylvia Brossoit.
California Highway Patrol dispatchers received a call at around 5:40 a.m. Sunday regarding a woman lying in the eastbound lanes of the freeway.
When detectives got to the scene, they discovered the victim was dead. It is unclear if the woman was killed and left on the highway or died as a result of being thrown out of a vehicle, said Lt. Don Slawson of the Los Angeles County Sheriff's Department.
Authorities are awaiting autopsy results to determine exactly how she died.
"What we're really concerned with at this time is trying to find anybody that may have been driving on the freeway saw something, notice anything unusual," said Slawson.
Though police do not know the exact cause of her death, thanks to the public's help, they were able to identify the victim. Edwinta Hereford used to live with her grandmother in Fontana, but she had moved several years ago.
Authorities are now trying to piece together her whereabouts, and they're hoping that the public will again be able to provide vital clues as to how the young woman ended up on the road.
