Supporters gathered behind a 16-year-old's defense attorneys after a court hearing Monday. 
 
 HOUSTON - The teen charged with murdering his parents at their Bellaire-area home appeared in court Monday. 
 
 The 16-year-old son of former Texas A&M All-American linebacker Antonio Armstrong and his wife Dawn was charged with murder Friday after the couple was found shot in their home. His name is not being released because his is a juvenile. 
 
 According to prosecutors, the suspect called 911 around 1:40 a.m. while hiding in a closet. The suspect claimed he saw a masked man inside the home. Prosecutors say police were skeptical because there were no signs of forced entry and the alarm was still set.

 According to police, the Armstrongs were shot in the head while they were in bed with a handgun that belonged to Antonio. A pillow had been placed over each victim's face. 
 
 Dawn died at the scene. Antonio was rushed to the hospital where he later died. 
 
 The gun was found by police on the kitchen counter with a scribbled note. The suspect admitted to playing with the gun in weeks prior to the shooting but denies his involvement in the crime. 
 
 The teen's 12-year-old sister was also home at the time and slept through the entire ordeal. 
 
 “It was kinda the all-American family," said HPD homicide detective Jimmy Dodson. "That’s why we’re trying to get down to figure out what’s going on in this household.” 
 
 Antonio starred for the Aggies in the early 90's before playing several years in the NFL and Canadian Football League. 
 
 Antonio was also a motivational speaker. He and his wife own 1st Class Training in Bellaire. Family, friends and clients created a makeshift memorial outside the gym over the weekend. 
 
 Antonio is also an associate pastor, according to police. Dawn Armstrong's Facebook page said they "serve in ministry together." 
 
 Relatives say they have another son that is college-aged. They have no idea what the motive could be.

 "There was nothing that even could have possibly justified this situation. There's nothing - this doesn’t even make sense, it makes no sense," Vaun Armstrong said. 
 
 Prosecutors say the charges could eventually be upgraded to capital murder. 
 
 A large group was in court to show their support for the teen. 
 
 The suspect is being held in detention until the next court hearing. A date has not yet been set.

– The 16-year-old Houston boy charged with murdering his parents called 911 himself around 1:40am Friday, telling dispatchers he was hiding in a closet after hearing gunshots and seeing a masked man inside the house. But police say when they arrived, the alarm was still set and there was no sign of forced entry; the teen actually disabled the security system to let them in, the Houston Chronicle reports. Police found former NFL player Antonio Armstrong and his wife, Dawn, shot in the head in their bed with pillows over their faces, KHOU reports. A gun belonging to Antonio had been used; police found it on a kitchen counter along with a handwritten note, but found no signs of a robbery or burglary. The suspect, who is not being named due to his age, admitted he had played with the gun in the weeks before the shooting, but insists he didn't kill his parents. Police arrested him Friday after he was "not able to give a convincing story of any kind," says the assistant DA. His 12-year-old sister was home at the time of their murders and slept through the incident. More than a dozen family members were in court for the teen's first appearance Monday; one called out, "We love you, man," as he was led away.
