YUMA, Ariz. – Authorities confirmed Tuesday that a Marine from Maine who was reported missing last week has been found dead in an irrigation canal in Yuma.

The body of Cpl. Joshua Barron, 22, was discovered by a farmer on Monday, said Yuma County sheriff’s Capt. Eben Bratcher. Barron was reporting missing March 16.

There was no sign of injury to the body, and nothing criminal is suspected, Bratcher said. Barron was initially identified because his name was tattooed on his shoulder. The Marine Corps helped to confirm his identity, and his wife, Natasha Barron of Standish, was notified. An autopsy is scheduled for today.

Barron was wearing civilian clothing, and it appeared that his body had been in the canal for at least several days, Bratcher said.

Barron was stationed at Marine Corps Air Station Yuma, where he was a Harrier jet mechanic. He lived off base.

His roommate last saw Barron on the evening of March 15, said Marine Capt. Staci Reidinger. When Barron didn’t show up for work on March 16, his commanding officer checked on him and found that he was missing. Military investigators were called. Yuma police were notified two days later by his mother, said police Sgt. Clint Norred.

Natasha Barron told the Yuma Sun that she spoke with her husband about 5 a.m. on March 16.

Later in the day, she saw that she had missed a call from her husband’s phone and called him back around noon. A woman answered the phone, and said she and her husband had found the phone while walking along a canal and were trying to return it.

Barron originally was from the Maine town of Cumberland and joined the Marines in July 2008, according to the service. After training as an aircraft mechanic, he was assigned to the base in Yuma.

The Marine Corps plans a memorial service on Thursday.
