The 16-year-old was charged as a juvenile and being questioned by investigators in connection with the deaths of Antonio and Dawn Armstrong.
Two of the couple’s other children were in the house when the shootings happened around 2 a.m. local time Friday and neither was hurt, the station reported.
“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.”
Police have not release the accused teen’s name because of his age.
Dawn Armstrong died at the scene, police said. Her husband was pronounced dead later at Memorial Hermann Hospital from a gunshot wound to the head.
Armstrong was a college football star at Texas A&M, where he played for the Aggies from 1991 to 1994.
The Miami Dolphins said in a statement that they were “saddened by the tragic” deaths.
