A Fort Riley soldier who was found unresponsive in his on-post residence was pronounced dead at a local hospital on Sunday.

Sgt. 1st Class George Bible III was a platoon sergeant and repaired Black Hawk helicopters. He is the eighth Fort Riley soldier to die since July 31st whose death either remains under investigation or has been ruled suicide, KTKA reports.

“We extend our heartfelt condolences to the family and friends of Sgt. 1st Class Bible, during this difficult time,” said Lt. Col. John E. Tiedeman.

Sgt. Bible, of Clarksville, Tennessee, joined the Army in March of 2002 and arrived at Fort Riley in February. The 36-year-old deployed to Iraq in 2006 and 2007 and to Afghanistan in 2008, 2011 and 2013.

Fort Riley officials say Bible’s death is under investigation.
