A U.S. Navy sailor was found hanging from a pipe outside a tool room aboard the USS Emory S. Land early Wednesday morning in La Maddalena, Sardinia, according to a 6th Fleet official.

The man, whose name was not released, was found by fellow sailors at around 1 a.m., but efforts to revive him were unsuccessful, said 6th Fleet spokeswoman Cmdr. Cate Mueller.

The U.S. Navy is investigating the incident.
