Antonio Armstrong, a former NFL player and later owner of several personal gyms, and his wife Dawn Armstrong were shot in their Houston home on July 29, 2016. Both were found in their bedroom with gunshot wounds to the head; Dawn was pronounced dead at the scene and Antonio, 42, later died at a hospital.

Investigators focused on the couple’s then-16-year-old son, AJ Armstrong. He initially told police he heard gunfire and saw a masked intruder, but officers found no evidence of a forced entry and the home alarm was still armed when first responders arrived; AJ disarmed it to let them in. A bullet hole was later found originating from AJ’s bedroom and passing through the ceiling into his parents’ room.

Does anyone have information about the Armstrongs, their activities in Houston, or the night of July 29, 2016 that could help clarify what happened?
