MILAN, Shawwal 7, 1437, Jul 12, 2016, SPA -- The body of a U.S. airman has been found in a river in the northern Italian town where he went missing 10 days ago, Italian and U.S. authorities said Tuesday, AP reported. A Carabinieri official, who spoke on condition of anonymity because he wasn't authorized to give the information, said the body of Staff Sgt. Halex Hale was identified by his father and colleagues from the Aviano Air Base. The body, clad in just a swimming suit, was spotted earlier Tuesday by a passer-by, who notified authorities. The U.S. Air Force confirmed that Hale's body had been found in the Livenza River, within a couple of kilometers (a mile) of where he went missing July 2. The cause of death is under investigation. "We are deeply saddened by this tragic loss of life," said Brig. Gen. Lance Landrum, commander of the 31st Fighter Wing, "Our thoughts and prayers are with his family, fellow Airmen and friends." The 24-year-old from Middletown, Indiana, who was assigned to Aviano Air Base north of Venice, went missing on July 2 after leaving a friend's cookout off base in the town of Sacile to walk to another friend's home about 15 minutes away. He left his cell phone, credit cards and car at the cookout. -- SPA 21:11 LOCAL TIME 18:11 GMT www.spa.gov.sa/w
