UPDATED: Bellaire businessman dies; teen son facing two murder counts for killing parents

UPDATE: Antonio Armstrong, 45, died Friday evening from what Houston police said were gunshot wounds inflicted overnight by his 16-year-old son. The young man had already been charged with murder in the death of his mother, Dawn, who was discovered dead in the bedroom of the family’s town home in the 5300 block of Palmetto Street, just outside the northwest city limits of Bellaire. A younger sister was at home but unharmed.
InstantNews was told that Armstrong, a former college and NFL football standout, had been on life support since he was brought in following the 2:15 a.m. shooting.
He and his wife founded the 1st Class Training fitness outlets, with the original in Bellaire a short distance from their home, and two other Houston locations. Armstrong, who was raised in the tough Kashmere Gardens area of Houston and prevailed to excel academically and athletically at Texas A&M, was a popular motivational speaker and a coach with the Southwest Football League.
He and his wife were active church pastors, and their son was involved in the Young Life religious organization and athletics at the exclusive Kinkaid School.
A 16-year-old son has been charged with murder in the early morning shooting death of his mother and the critical wounding of his father — a onetime football star who became a popular Bellaire business owner and youth football coach.
Houston police investigators termed the teen, his parents and two other children “an all-American family” and said the call shortly after 2 a.m. Friday to a town home on Palmetto Street at Mapleridge, just outside Bellaire, was the first they had ever received.
The parents are Antonio and Dawn Armstrong; as a juvenile, the son’s name has not been released. Officers found the mother dead in a bedroom and the father critically wounded. He was transported to Memorial Hermann Hospital in the Texas Medical Center.
The Armstrongs are founders of First Class Training, a gym in Bellaire which they have operated for 11 years. Antonio Armstrong, according to an online biography, was a linebacker for Texas A&M, where he earned honors for his play in the 1994 Cotton Bowl, and the Miami Dolphins.
Armstrong has coached in the Southwest Football League for youth for a decade, and is also a strong supporter of the Bellaire Little League.
