The Sacramento County Coroner’s office identified one of the victims as 18-year-old Naiomi Michelle Brown. The other victim who died has not been identified.

Based on statements made by people on the scene, there are unconfirmed reports that they might have been teenagers. A friend of the victim says three of the people were recent high school graduates and the fourth was a current senior.

Henoch Munoz, who lives across the street from the crash, says he woke up to what sounded like an explosion. He says people often treat the road as a speedway.

“This morning I came out to see and I saw the car there so (I) just came here and it seems worse than I thought,” Munoz said.

Karl Ortega thinks about the families of the four people who were inside the car, trying to put into words what all are now going through.

“This is really, it’s horrific,” he said.

Friends are planning a memorial for Tuesday to both remember the lives lost and rally for the survivors of the crash.
