A hit-and-run driver killed three teenage girls trick-or-treating Friday night in Southern California.

Authorities said the girls were walking in a crosswalk in a busy intersection near an elementary school in Santa Ana, about 30 miles southeast from downtown Los Angeles, around 6:45 p.m. when an SUV with two men inside hit them.

Police spokesman Anthony Bertagna said that the vehicle was moving at a "high rate of speed" when the crash occurred.

The three girls' names were not immediately released, but Orange County Fire Capt. Steve Concialdi said they ranged in age from 13 to 15. Two of them were pronounced dead at the scene, and the third victim died as paramedics were getting ready to take her to a nearby hospital, Concialdi said.

"[This incident was] very sad," Concialdi said. "When millions of children, teenagers and adults are out trick-or-treating on a wonderful evening to insert tragedy like this."

The SUV was found abandoned near the intersection where the girls were hit, but the two suspects have not been found yet. Police are looking for the two men who were in the SUV when the accident occurred, police Chief Carlos Rojas said at a media conference.

Police said they were still working to determine the girls' identity and alerting their parents, according to Bertagna.

A parent, Jeff Evans, was trick-or-treating with his 8-year-old daughter only a block away when he heard the squealing tires of the SUV. He looked over and saw the collision.

"When we got over here, there was already a tarp over two girls," Evans said to the Orange County Register.

Following the accident, nearly 60 people gathered at the intersection, which had been closed to clear the incident. The fire department had chaplains and other volunteers to help counsel those upset or in shock after witnessing the accident.
