Investigators are continuing to search for a 25-year-old San Gabriel Valley man who allegedly attacked a woman Sunday and forced her into the trunk of her own car before she escaped by jumping out of the car as it sped down the 57 Freeway.

The man’s name was known, sheriff’s officials said, but was not released Monday as officials continue to investigate. Detectives also declined to release information on the victim’s car, which the suspect may still be driving.

The victim, a 21-year-old area woman, was also not named.

She left a party in unincorporated Covina with the man when officials believe he struck her in the head with a blunt object, knocking her unconscious.

She woke up in the trunk of her own car and was able to get it open, then jumped from the trunk as the car continued at freeway speed on the 57 Freeway, north of the 60 Freeway in the Walnut area.

Officials said the woman suffered severe road rash, but no critical injuries.
