Armstrong Jr. pleaded not guilty and has maintained his innocence since his parents’ deaths. He “adamantly [denies] that he has committed these murders,” defense attorney Rick Detoto told PEOPLE previously.
Armstrong Jr. sobbed hysterically when prosecutors showed autopsy pictures of his parents in court Thursday, local station KTRK reports.
Before resting its case on Thursday, the prosecution presented dozens of text messages between the teen and his parents in the 10 months leading up to their deaths showing their disapproval and disappointment in him over his performance and behavior in and out of school, KTRK-TV reports.
The teen was a “standout” on the football field in middle school at The Kinkaid School, the private school in Houston that he attended until the end of his junior year, his former coach testified.
In his junior year in 2016, when the teen was struggling in school, his father texted him, saying, “You can’t feel hopeless. You have to believe in yourself like we believe in you,” KTRK reports.
But his father expressed disappointment when he learned that his son had failed to hand in assignments and skipped extra help sessions.

His mother texted back, “We gave you all and the best we had. We wanted the best for you. We provided the best education, bought you a great car to celebrate you. We tried to be open with you and what was important to you, and all you do is lie to us, scheme behind our backs.”
“Beyond disappointed,” she texted.
Prosecutors say the boy was not readmitted to his school because of his poor academic performance, the Chronicle reports. His attorneys say the family could no longer afford the $30,000 a year tuition.
He was due to attend public school in the fall of 2016, the Chronicle reports.
Prosecutors are not commenting during the trial. Attempts to reach the teen’s attorneys for comment were not immediately successful.
