Two of Antonio and Dawn Armstrong's other children were in the house when the shootings occurred at around 2 a.m. local time Friday, according to KPRC. Neither child was harmed.
An investigator who spoke with KPRC called the Armstrongs an "all-American family" and expressed shock at the horrific incident.
"This was an outstanding family," Houston police homicide investigator Jimmy Dodson told KPRC. "He was an associate pastor in the area church. He's a great guy. The mother was apparently a great mother, according to family members."
Dawn Armstrong died at the scene, according to police. Antonio Armstrong sustained a gunshot wound to the head and was pronounced dead later Friday at Memorial Hermann Hospital.
The teen's motive has yet to be determined.
Before joining the NFL, Armstrong was a star college football player at Texas A&M , where he played from 1991 to 1994. He was a key force in school's famous "Wrecking Crew" defense.
Armstrong was named first-team Associated Press All-America linebacker in 1994 and was drafted in the sixth round of the 1995 NFL Draft by the San Francisco 49ers.
In the wake of Armstrong's untimely death, Texas A&M University Athletics Department released a statement expressing grief for the the family's devastating loss.
"Our thoughts and prayers are with Antonio Armstrong and his family, his old teammates and the entire Aggie family," Texas A&M head coach Kevin Sumlin said. "Our strength coach Larry Jackson was a teammate of Antonio's and thought the world of him. This is a terrible tragedy and our hearts are broken."
"Antonio was a special young man," former Texas A&M head coach R.C. Slocum, who coached Armstrong at Texas A&M, said. "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."
Police have not released the accused teen's name because of his age.
