FORT IRWIN - The long line of vehicles waiting to get out of Fort Irwin at the end of the work day on Thursday stems from an investigation by Fort Irwin law enforcement.

Col. Chris Philbrick, the garrison commander, said authorities are searching for a suspect in a morning incident at Fort Irwin. Philbrick could not go into further detail about the incident because it is under investigation. A sergeant with the Fort Irwin Police Department said the suspect is wanted in connection with a suspected assault that occurred.

The sergeant, who would not identify himself, said the suspect is a Hispanic man, about 5 feet, 8 inches tall, weighing 130 to 140 pounds. The man was last seen wearing a brown shirt and blue jeans. The police do not whether he is a civilian or enlisted military.

Philbrick said security officers at the gate exiting Fort Irwin are checking identification of the people inside the vehicle and asking questions about the suspect's whereabouts. Post spokesman John Wagstaffe said the line of vehicles stretched from the gate to the post's commissary around 5 p.m. and added approximately an extra hour to the evening commute.

Anyone with information about the incident or the location of the suspect can call the Fort Irwin Police Department at 380-4444. To remain anonymous, call We-TIP at 1-800-78-CRIME.
