Antonio Armstrong, who graduated from Texas A&M and spent one year in the NFL, and his wife were shot and killed Friday morning. Their 16-year-old son has been charged with murder, per KTRK in Houston.

Armstrong's wife, Dawn, died, while Antonio was hospitalized and in critical condition.

Texas A&M announced later in the day Armstrong succumbed to his injuries. Former Aggies head coach R.C. Slocumb commented on Armstrong's passing:

Antonio was a special young man. He was an All-American and an outstanding player, but he was an even better person. He was such a positive influence on his teammates. He always had a great big smile and was a joy to coach.

Investigators have yet to determine a motive.

ABC 13's Courtney Fischer shared photos of the crime scene:

In his senior year with the Aggies in 1994, Armstrong was an Associated Press All-American. The San Francisco 49ers selected him in the sixth round of the 1995 NFL draft, and he went on to play four games for the Miami Dolphins in '95.
