​Based on the preliminary investigation, Khanh Van Le, 39, of Anaheim, was told to leave the party because he was trying to start a fight with another partygoer. But he returned on two separate occasions, tried to cause trouble at the party and ultimately got into a physical confrontation with a man he apparently did not know, Anh Tuan Nguyen, 37, of Long Beach, said police Capt. Mike Handfield.

Police were called and outside Saigon Towing officers encounted Le, who claimed he was leaving the party after having been assaulted. He told officers his attacker had already left and that Le did not want to press charges, Handfield said. With that, Le was gone, but officers soon discovered from other partygoers that the man they had just cleared had allegedly stabbed Nguyen, Handfield said.

Then, at about 8:15 p.m., officers were called to assist paramedics with a man who was down in the street nearby. Officers arrived to find Nguyen lying next to a 1998 Toyota Sienna he'd been seen driving before the stabbing. Rescue efforts failed to save the man, who died at the scene.

Armed with a search warrant, officers went to a residence at 246 S. Florette, Anaheim, where Le was taken into custody and later booked into Orange County Jail on suspicion of homicide.

Officers believe Le returned the party a third time, spotted Nguyen driving away, approached him and stabbed him in the driver's seat of the Toyota, causing the victim to fall onto the roadway. Witnesses told investigators that Le was driven to and away from the location by a woman. His girlfriend, Thao Nguyen, was also arrested.

They are scheduled to be arraigned at the West Justice Center on Wednesday.
