On July 29, 2016, when 16-year-old A.J. called 911 to report the horrifying discovery of his parents, Dawn and Antonio Armstrong Sr., shot in their bedroom. A.J. claimed he heard two gunshots, prompting the urgent call for help. However, the case took a dark turn when investigators found peculiar details at the crime scene.

As A.J. recounted a masked intruder in the house, investigators found no evidence of forced entry. The alarm system, initially armed, was disarmed by A.J. upon police arrival. The crime scene presented a chilling note proclaiming, “I HAVE BEEN WATCHING YOU FOR A LONG TIME. COME GET ME.” The mysterious circumstances surrounding the murders set the stage for a protracted legal battle.

The legal proceedings commenced in March 2019, with A.J. being tried as an adult. Two mistrials followed in April 2019 and October 2022, each marked by prolonged jury deliberations and an inability to reach a unanimous verdict. A.J.’s life continued, marked by marriage, fatherhood, and the weight of an ankle monitor tracking his every move.

As the third trial began in July 2023, the court faced a hiatus to consider new evidence. Seven years after the gruesome murders, the jury returned a unanimous guilty verdict in August 2023. A.J., now 23, received a life sentence with the possibility of parole after 40 years.

Family Dreams

Antonio Armstrong Sr., a former NFL player turned motivational speaker, and his wife, Dawn, portrayed the image of a perfect family. The Armstrongs, deeply rooted in faith, family, and football, were known and respected in the Houston area. However, the family’s idyllic facade shattered in the months leading to the murders.

Antonio Jr.’s struggles at Kinkaid and accusations of substance abuse strained the family dynamic. Josh, the older brother, faced his own challenges with marijuana use and college dropout. The once All-American family found itself grappling with internal turmoil.

A Family in Crisis

Antonio Jr. set a fire outside his parents’ bedroom and fired the murder weapon through a pillow, concealing the hole in his bedroom floor. These events, coupled with cell phone records placing Antonio Jr. awake and moving around the house before the 911 call, formed a compelling narrative for the prosecution.

Despite efforts by the defense to shift suspicion to Josh, jurors found the prosecution’s argument convincing. Josh’s deteriorating mental health post-murders painted him as a victim rather than a perpetrator in the eyes of the jury.

Blood Stains

Discovery of bloodstains on A.J.’s shirt, detected just before the third trial. Prosecutors argued that the blood matched Antonio Sr.’s, providing a pivotal piece of evidence. A.J.’s defense countered, claiming the blood could be a result of cross-contamination.

Blood pattern analyst Sgt. Celestina Rossi testified that the bloodstains originated from Antonio Sr.’s final moments. The courtroom drama unfolded as the defense navigated this last-minute revelation.
