An off-duty security guard shot three men, killing one, during a possible robbery attempt Friday morning in Lynwood.
Officers responded to the shopping center parking lot in the 10900 block of Long Beach Boulevard about 4:45 a.m.
According to the preliminary investigation, the security guard was sleeping in a vehicle and shot the men when they tried to rob him, the sheriff's department reported. The men approached the guard's vehicle after pulling up in two pickups, investigators said.

"The security guard's vehicle windows were extremely tinted," sheriff's Lt. Scott Hoglund told reporters at the scene. "It is unknown at this time if the suspects knew that the victim was inside the car at that time or not."
The security guard left the scene and called the sheriff's department, according to investigators. The guard was being questioned early Friday.
"At this point, he is a victim," Hoglund said. "The legality of him carrying a firearm and his actions during the shooting will be investigated."
The other men were taken to a hospital. Their conditions were not immediately available.
