Dawn Whitely Armstrong, 42, and her husband Antonio Armstrong, 43, were killed on July 29, 2016, in their Houston home. Both were active in the community, owning several gyms and ministering at their church. Antonio was a former NFL player.

Their 16-year-old son, AJ Armstrong, was initially identified as the lead suspect and charged with two counts of capital murder. He told investigators he had seen a masked intruder, but no evidence of an intruder was found. The home alarm was still armed when first responders arrived and AJ was the one who disarmed it. Investigators also reported a bullet hole that started in AJ’s bedroom and penetrated the ceiling of his parents’ room.

The case went to trial three times, with the first two trials ending in mistrials; in a third trial prosecutors presented new evidence that led to AJ Armstrong’s conviction. The family’s deaths drew extensive media attention and community support.

Did anyone know the Armstrongs’ routines or household layout well enough to help clarify the timeline that night?
