Brad Henry Coolack, 35, was shot and killed in his Houston apartment on March 11, 2022. Paramedics pronounced him dead at the scene after he was found with multiple gunshot wounds; investigators reported he was shot at close range in the back and three shell casings were recovered on the bedroom floor.

Police identify Brad’s older brother, Kyle Andrew Coolack, 37, as the suspect. Witnesses said an argument was overheard between the brothers just before the shooting, with one of them yelling that the other had slept with his wife. Kyle reportedly fled the scene, was later found walking along a highway in Calhoun County, Iowa, admitted to the killing, and was taken into custody by a deputy. The investigation also notes a prior incident months earlier in which Kyle pistol-whipped Brad.

Anyone who knew Brad or observed activity around his Houston apartment on March 11, 2022, or who has information about the relationship between the brothers is asked to share what they know.
