The friends of a teenager accused of fatally shooting his parents say he didn't have it in him to kill anybody.

In probable cause court this morning, Eyewitness News learned it was their son who called police at 1:41am Friday.

Antonio Armstrong's mother leads service where he was assistant pastor.

The teen allegedly told police he heard gunshots in his parents' bedroom and that he went inside a closet on the third floor. His sister, meantime, was sound asleep in her second flood bedroom.

Police say it was the teen who allowed them inside the home when they arrived, and that Armstrong's son had to turn off an expensive security system to let them in.

Officers were not convinced by the teen's story, at one point allegedly claiming he saw a masked man inside the house.

Friends gather at memorial for the Armstrong family, Kaitlin McCulley reports.

The Armstrongs were found shot inside their bedroom, both with pillows over their faces. Dawn Armstrong was dead by the time police found her.

A .22 caliber handgun was also found on a kitchen counter, along with a handwritten note. We have yet to learn what the note said, but we were told the bullet casings found in the bedroom matched the gun.

Detectives claim the suspect admitted to experimenting with silencing the gun with blankets and pillows in recent days.

The 16-year-old suspect is charged with murder, but capital murder is a possible upgrade after his father later died at a hospital.

The teen will not be released at this time.

The 16-year-old's attorneys says the teen did not kill his parents.

"He's a great kid from a good family. There's absolutely no motive why this happened. It doesn't make sense," said Rick DeToto, one of the defense attorneys.

"Everybody wants answers right now. We can't provide those answers right now because the facts haven't come out yet," said Chris Collings, also part of the defense team.

There was some discussion about upgrading the murder charges and trying the teen as an adult. Right now, he's still in the juvenile system, but there's a strong possibility his charges will soon be upgraded.

"He's charged with murder now. The respondent's father passed away. That was the second person. Obviously that makes capital murder a possibility. I can't speak to whether or not that will occur in this case," said John Brewer, Harris County Assistant District Attorney.
