Yesuah Boerstler, 18, suffered crushing head injuries sometime Wednesday night or early Thursday, and died Friday at Maui Memorial Medical Center, said Lt. Glenn Cuomo of the Criminal Investigation Division. There were no other injuries, he said, and the autopsy did not find signs of an assault. Boerstler did have alcohol in his system, and further testing will be done to determine whether he ingested other substances, Cuomo said.

Still to be determined is whether Boerstler's death was accidental. Police have not identified the motorist who ran over him.

A passerby found an unconscious Boerstler at about 8 a.m. Thursday, and he was taken to the hospital.

Pa'uwela Point is one of several areas on Maui's north and east coastlines where groups of young people, many under the legal drinking age of 21, are known to party, said Lt. Mollie Klingman of the Maui Police Department's Juvenile Section.
