A San Diego man who received a vicious beating before a concert last fall is suing the venue’s operator and security services for failing to prevent the incident.

Zac Zander was tailgating in the parking lot of the Cricket Wireless Amphitheatre (now known as the Sleep Train Amphitheatre) prior to a Jason Aldean concert when he says he tried to stick up for a group of girls who were being verbally abused by several men. The perpetrators allegedly turned their attention to Zander, breaking several bones in his face during a brutal beating.

Zander told NBC San Diego that his injuries required “upwards of 20-something screws in [his] face, with a few plates [and a] bone graft,” and that he still cannot feel parts of his face.

He is now seeking damages from Live Nation Entertainment Inc., which operates the amphitheater, and Staff Pro, a staffing agency that provides event security, claiming that they failed to provide adequate security in the parking lot prior to the concert. His attorneys also accuse Live Nation of encouraging over-the-top tailgating celebrations to increase alcohol sales.

Raymond Sharkey, a Marine sergeant stationed at Camp Pendleton, was charged with assault and battery in the case in May.
