Two Brigham Young University students remain hospitalized including one in critical condition following a head-on collision Monday afternoon that killed three other BYU students riding in their compact car.

The five were returning to the Provo campus after spending Easter weekend in California when their compact car collided with a semi-trailer truck hauling lumber. The accident occurred at 3:22 p.m. on SR-18, six miles west of Victorville.The injured passengers are Johnson Chun-Sing Tong, a 22-year-old sophomore from Walnut Creek, Calif.; and Rebeca Ann Burraston, a 20-year-old sophomore from Tucson, Ariz. Tong, who suffered massive head injuries, remains in critical but stable condition at San Bernardino County Medical Center, while Burraston was upgraded to fair condition at Loma Linda University Medical Center.

Killed were Ross Evan Williams, an 18-year-old freshman from Calabasas, Calif.; his brother, Daniel James Williams, a 20-year-old sophomore from Calabasas; and Karen Joyce Hanks, a 19-year-old sophomore from Fullerton, Calif.

The younger Williams was driving the vehicle, and the three were pronounced dead at the accident scene. Burraston and Hanks were roommates at BYU.
