Thomas Powley, 58, was shot and killed on July 5, 2017, in the backyard of a home on San Angelo Drive in Benbrook. Police were called about 11:45 a.m.; they found Powley deceased and another man with a gunshot wound to the leg.

The suspect named in reports is Powley’s brother, John Lawrence Conroy (also shown as John Conroy), 56. He was located barricaded inside the residence and held officers at bay for almost four hours. Conroy made threats toward officers and himself and exchanged gunfire briefly with police; no officers were hurt. He surrendered at about 3 p.m. and was later charged with his brother’s murder. Motive had not been disclosed at the time.

Anyone who knew Thomas Powley, the family, or who has information about the events that day is asked to come forward.
