Authorities say a security guard was killed and two other men wounded in a shooting outside a New Year's Eve party at a Southern California roller skating rink.

The San Bernardino County Sheriff's Department says it's looking for suspects in the early Thursday shooting at the party of about 200 people at Cal Skate in Grand Terrace. Signs outside the venue advertised a late-night skating party that had just ended when the gunfire broke out.

Deputies found three injured victims — two of whom were security guards — outside the party. One of the guards, 48-year-old Richard Williamson of Riverside, died at a hospital about an hour later.

The other victims were a 28-year-old and a 22-year-old. One was treated at the scene, and the other was hospitalized. Their names haven't been released.
