MINOT AIR FORCE BASE – An airman stationed at Minot Air Force Base sustained injuries on Wednesday and was taken to a Jackson, Calif., hospital.

The Public Affairs Office at Minot AFB issued a statement on Friday saying the airman, who is assigned to the base’s 91st Missile Wing, was on leave in California when he was injured. He was previously assigned to Travis AFB in California.

The incident is currently under investigation by the Sacramento Police Department, according to the Minot AFB statement.

Minot AFB officials did not release the name of the airman. California law enforcement officials released his name.

News media in the Sacramento area reported that Keith Keiffer, 32, who is with the missile wing at Minot AFB, was “barely conscious,” had a head injury and didn’t know his name or where he was when he was found in a ditch near Pine Grove, Calif., on Wednesday. Initially, police there referred to him as “John Doe.”

Pine Grove is a small community on State Highway 88 in the foothills of Amador County, Calif. The community is about 50 miles southeast of Sacramento.

According to reports from California media, Sacramento Police Department detectives said Thursday he was starting to remember things that day and he told them he may have been the victim of a more serious crime that happened in the Sacramento area. After posting the story and a photo of Keiffer on Facebook, police learned he was an airman previously stationed at Travis AFB, Calif. Police are trying to confirm his claims that he was the victim of a serious crime in the Sacramento area. Police said Kieffer was in Sacramento to get a U-haul vehicle to move personal belongings to his new assignment. The airman had no wallet or identifying information on him. He had $30 in his pocket. It was reported he’s originally from West Virginia.

Keiffer was transferred out of the Jackson hospital and in the care of Travis AFB, a Sacramento TV station reported on Thursday.

A spokesman for the Sacramento Police Department said in an email on Friday that their investigators have spoken with Keiffer in an attempt to get information but at this point they didn’t have enough information to determine where the alleged took place. “Our detectives will work on our end to see what/if anything occurred in the city limits of Sacramento,” he said.
