A Joint Base Elmendorf-Richardson airman arrested Tuesday evening in connection with the disappearance of Senior Airman Clinton Reeves allegedly lied to investigators, destroyed bloody clothing and moved Reeves' car, according to charging documents.

Reeves was last heard from April 22; he has been listed as missing since April 23, when he failed to report for duty. Anchorage police said Tuesday that detectives believe Reeves was the victim of foul play, but have not confirmed whether a man's body found Tuesday in Eagle River is that of Reeves.

Airman James Thomas, 24, faces six felony counts of tampering with physical evidence in connection with the Reeves case, and is now considered a person of interest in his disappearance. Maj. Joseph Coslett at JBER confirmed that Thomas is also a JBER airman, but said Wednesday afternoon that Thomas and Reeves are not in the same unit.

According to the documents (PDF), Thomas told APD homicide detectives that he had last seen Reeves on April 19, and received a text message from Reeves which said he was ill and receiving medical attention.

After analyzing Reeves' cellphone, investigators learned that it had been in the vicinity of Thomas' residence on the night of April 19, which was "inconsistent" with what Thomas had told police.

Detectives executed a search warrant on Thomas' home and discovered evidence of a violent incident inside, as well as evidence that the carpet had been recently cleaned. During a Friday interview at APD headquarters, Thomas allegedly continued to deny any knowledge about Reeves' disappearance -- then said that when he came home, Reeves was "at his residence with an unknown individual" before ending the interview.

Thomas then contacted law enforcement with the U.S. Air Force Sunday and gave a different account of what happened.

"Instead, he stated that when he arrived home on the night of April 19, 2012, Reeves was lying on a loveseat with a towel over his head," prosecutors wrote. "Thomas stated that 'an unknown man' was inside the residence holding a gun. Thomas stated that the gunman held him at gunpoint, had him turn around, and ordered Thomas not to move. According to Thomas, the gunman and Reeves then left the residence. Thomas claimed not to know if Reeves walked out of the residence or if he was carried."

Thomas told investigators that he subsequently started to clean up blood form the house, wiping the loveseat, couch and carpet clean with towels, rags and paper towels and using a carpet cleaner in an attempt to clean the carpet. During the cleanup, he got blood on two sets of clothes.

"Thomas then threw the towels, rags, and paper towels in a dumpster," prosecutors wrote. "Thomas then removed the loveseat from the residence and dumped (it) in at a dumpster in a different area of town, close to where he had discarded the rags. Thomas took the bloody clothes to a different residence, cut them up and burned the clothes in the fireplace."

In addition to conducting the cleanup, investigators say Thomas also moved Reeves' vehicle to where it was found and seized by APD on April 27, on the 200 block of McCarrey Street.

"Thomas said that he did not want Reeves' vehicle parked in the apartment parking lot, so he drove it over towards (McCarrey) Street and left it there," prosecutors wrote.

According to the charging document, Thomas never mentioned his involvement in cleaning up the residence until Monday.

Thomas denied being involved in Reeves' disappearance. He is being held on $25,000 cash bail, with a court-approved third-party custodian required for release.
