After Antonio and Dawn Armstrong were fatally shot in their Houston home early Friday, their 16-year-old son was taken into custody, multiple outlets report.

According to the Houston Chronicle, Dawn was found dead in the couple’s bedroom. Antonio, a former football star, was taken to Memorial Hermann Hospital in critical condition and died there several hours later.

Police told local news station KTRK that the Armstrongs’ teenage son had been charged with murder, though no motive had been identified. The 16-year-old was also the one to call 911 around 1:30 a.m. Friday.

A source close to the investigation told KTRK a note reading, “I’ve been watching you,” was found near the still-smoking gun in the family’s home.

“There was nothing left out, there was no neglect or anything, nothing that could even possibly justify the situation,” Dawn’s cousin Vaun Lee told KTRK. “This makes no sense. No sense.”

Local media outlet KPRC2 reported that the couple had two other children, both of whom were in the home at the time of the shooting. Both were unharmed.

“This was an outstanding family. The male of the family was an absolute hard-working breadwinner. He was an associate pastor in the area church. He’s a great guy,” Houston Police Department homicide investigator Jimmy Dodson told KPRC2. “The mother was apparently a great mother, according to family members. Like I said, it was kind of the all-American family.”

Investigators said there was no sign of struggle in the bedroom and no sign of forced entry into the home.

Antonio, who played linebacker for the Texas A&M Aggies and the Miami Dolphins, was remembered by former A&M head coach R.C. Slocum.

“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,” Slocum said in a statement released Friday afternoon on Twitter.

Family friend Scott Binkley expressed shock and sadness over the Armstrongs’ deaths, describing the pair, who owned the First Class Training gym in Houston, as pillars of the community.

“Fantastic people. I have no idea why this would be happening to them,” Binkley told KPRC2. “He was one of A&M’s top 25 athletes, served the Lord, worked in the community, did nothing but help people constantly. We are just shocked at what happened.”
