Military officials have released the name of a battlefield surveillance unit leader who was killed by a fellow soldier during a safety briefing at Fort Bragg.

Authorities say 42-year-old Lt. Col. Roy Tisdale of Alvin, Texas, died immediately after being shot Thursday, and the shooter then turned the gun on himself.

Tisdale took command of the 525th Brigade Special Troops Battalion when it was activated in January. He was commissioned as an infantry officer after graduating in 1993 from Texas A&M University.

Special agents from the Army Criminal Investigation Command are investigating the shooting.

The shooter is in custody, but his name and condition have not been released.

A third soldier, 22-year-old Spc. Michael E. Latham of Vacaville, Calif., also was wounded and has been released from the hospital.
