The U.S. Coast Guard says a crewman from Virginia assigned to a cutter stopped in Dutch Harbor died over the weekend.

Seaman Ethan Kelch, assigned to the cutter Douglas Munro, was found unresponsive on the west side of Amaknak Island near Unalaska Island Saturday night. According to a Coast Guard statement, medics performed CPR on Kelch and transported him to a local clinic, but the 19-year-old was pronounced dead early Sunday in Dutch Harbor.

"The Coast Guard is deeply saddened by the tragic news that we lost one of our own," said Rear Adm. Matthew T. Bell Jr., commander of the Coast Guard's 17th District. "As we mourn his death, we send our deepest condolences to Seaman Kelch's family and loved ones."

Kelch was initially reported missing Saturday night after he didn't show up during normal hours. 

Crew members conducted a ground search and a helicopter crew attached to the Douglas Munro, which has been stopped in Dutch Harbor awaiting repairs, was launched to search by air. Local Unalaska fire and police personnel assisted in the ground search.

The Coast Guard is investigating and working with local authorities to determine Kelch's cause of death.
