Los Angeles County prosecutors charged a 40-year-old man with sexually assaulting two women in his van in a secluded part of the Angeles National Forest earlier this week.

Eduardo Sarabia was charged Wednesday with one count of forcible rape and one count of forcible oral copulation, according to court records. Sarabia is accused of raping a woman after driving her to a concealed area of the forest on Sunday and then sexually assaulting a second woman in the same remote area on Monday, Los Angeles County Dist. Atty. George Gascón’s office announced in a news release. The incidents took place along Highway 39 between the hours of 9:30 p.m. and 10 p.m. authorities said.

“The horrific and violent sexual assault that these two survivors endured by the alleged suspect is deeply troubling and incomprehensible. Our thoughts are with the victims during this tremendously difficult time,” Gascón said in a statement on Thursday.

The Los Angeles County Sheriff’s Department is asking for the public’s help to find any additional victims. Based on the circumstances surrounding the case, investigators believe there could be more unidentified victims. The Sheriff’s Department released images of Sarabia and his windowless white-paneled van.

“I want to emphasize that this is an ongoing investigation, and there may be additional victims who have yet to come forward. I urge anyone who has been affected by similar incidents to contact law enforcement and seek available resources,” Gascón said.

Sarabia was arraigned in a Pomona courtroom Wednesday and is due back in court June 27. Anyone with information about this case can contact the Sheriff’s Department, Special Victims Bureau at 877-710-5273 or by email at [email protected].
