Ramiro "Ray" Martinez (born January 20, 1937) is a former Austin Police Department officer whose actions ended the University of Texas tower shooting spree, when he and other officers reached and killed sniper Charles Whitman on August 1, 1966.
Martinez was born in Kent County, Texas and graduated from Rotan (Texas) High School in 1956. He enrolled in the University of Texas at Austin, but dropped out for financial reasons. After three years as a combat medic in the United States Army, he joined the Austin Police Department, graduating from the police academy in 1961.
Martinez was off duty on August 1, 1966, when he learned via television of the Texas Tower sniper shooting. Arriving at the campus, Martinez went to the top of the tower with civilian Allen Crum. Martinez dislodged a dolly used by Whitman to block the door that led to the observation deck of the Main Building tower at the University of Texas at Austin. Martinez and Crum went out the door, and as Crum guarded the South side, Martinez went around the Southeast side to find the shooter(s). Officer Houston McCoy came to the top of the tower with Officer Jerry Day. Crum told the officers where Martinez was. McCoy, armed with a shotgun, caught up with Martinez and they noticed Whitman sitting in an opposite corner. Martinez jumped out and fired in the direction of Whitman, missing with all of his revolver shots. McCoy leaped out while Martinez was firing and saw Whitman's head looking over the light ballast, McCoy fired at the top of the ballast, hitting Whitman between the eyes with several pellets, killing Whitman instantly.
