A Fort Riley private has been charged with murder in the death of a fellow soldier from his unit.

Officials at the northeast Kansas post announced the charge Thursday against Pvt. John Hughes. He’s also charged with larceny and resisting arrest.

Hughes is accused of killing 21-year-old Pvt. Thomas Lavrey, who was found unresponsive in his living quarters on May 14. The Army has not disclosed the cause of death but says the investigation continues.

Hughes is being held at Fort Leavenworth. Members of his defense team could not be located for comment Thursday night.

Lavrey was a native of West Seneca, N.Y.

Both were assigned to Special Troops Battalion, 1st Sustainment Brigade, 1st Infantry Division – Lavrey as a utilities equipment repairman and Hughes as a wheeled vehicle mechanic.
