A man with a high-powered rifle lured the officers to his mobile home last night with a bogus 9-1-1 call and shot them.
D-P-S spokesman Mike Cox says Jeremiah Engleton of Pleasanton died after shooting himself, but also was hit by police gunfire.
The call came from Engleton's mobile home.
Engleton had been jailed earlier yesterday on a domestic violence charge.
Atascosa County sheriff's deputies Mark Stephenson and Thomas Monse approached the home and were immediately fired upon from nearby underbrush.
Engleton then apparently grabbed a pistol from one of the fallen officers and returned to the brush.
D-P-S Trooper Terry Miller arrived at the scene and called for backup after spotting the slain deputies. But Cox says before Miller could remove his seat belt -- he was shot to death through a driver's side window.
The slain deputies also were still in their car.
Officers used searchlights and a police helicopter with infrared sensors to find the gunman, who continued to snipe from his hideout.
Engleton turned the gun on himself just before police shot him.
Authorities found him with an additional shotgun and a sack of ammunition.
Two other lawmen suffered non-life- threatening wounds.
Miller was the 74th D-P-S officer killed in the line of duty and the first since 1994.
It's the worst tragedy involving lawmen since the February of 1993 Branch Davidian assault near Waco that left four federal agents dead.
Six Davidians also were killed in the assault that led to a 51-day siege. The standoff ended on April 19th of 1993.
