YAKIMA, Wash. — A soldier died Thursday at the Army’s Yakima Training Center, but few details about the death were released by the military.

Yakima County Coroner Jack Hawkins said he was told by military officials that the soldier had shot himself.

Hawkins said he was told by military officials to hold off on any initial probe of the incident until an investigator from Joint Base Lewis-McChord, south of Tacoma, arrives.

“They like to do their own investigations,” Hawkins said.

The incident is under investigation, and the soldier’s name is being withheld pending notification of the next of kin, according to a news release issued by 364th Expeditionary Sustainment Command, which includes more than 40 Army Reserve units across the West.

The soldier belonged to the 364th, which includes nearly 4,000 reservists in Washington, Oregon, Montana, Idaho, Utah, Colorado and Wyoming.

“The injury or death of any soldier is tragic, and our thoughts and prayers go out to the soldier’s family at this difficult time,” Brig. Gen. I. Neal Black, the 364th’s commanding officer, said in the release.
