A Fort Wainwright, Alaska, soldier died of his injuries on Monday at Joint Base Lewis-McChord, Washington, where he was being treated, according to a Wednesday release from U.S. Army Alaska.

Sgt. Brian Sawyer, 33, was injured Feb. 3 in his on-post home, the release said, but the seriousness of his condition required a transfer to Madigan Army Medical Center, the release said.

“The Flying Dragon family grieves together today at the loss of one of our own,” Lt. Col. Jorge Rosario, Sawyer’s battalion commander, said in the release. “Sgt. Brian Sawyer will be greatly missed and our prayers are with his family and friends.”

His cause of death is under investigation, according to the release.

Sawyer had been assigned to 1st Battalion, 52nd Aviation Regiment since November 2016.

He joined the Army in 2010 and had served in Ansbach, Germany, and at Hunter Army Airfield, Georgia. He deployed to Afghanistan in 2012, according to the release.

His awards included the Army Achievement Medal, two Good Conduct Medals and the Combat Action Badge.
