Car enthusiasts gathered in the parking lot, burning rubber, and as video shows, carrying balloons filled with nitrous oxide to be inhaled by partygoers to get high, Fullerton police said.
Amid the event, a fight broke out involving Jefferson Sanchez and he was stabbed, police said.
"The victim was transported to a local hospital by partygoers and we were called to the hospital," said Fullerton police Sergeant Kathryn Hamel. "Unfortunately the victim was pronounced dead."
Police said by the time officers arrived at Anaheim Regional Hospital, there were no friends or witnesses left to tell them exactly what happened.
Authorities still don't know who organized the car club meet.
