HOUSTON, Texas (KTRK) -- Understanding the Armstrong family's ADT home security system is an essential part of A.J. Armstrong's capital murder trial. But, the records are tedious, monotonous, and complex-a lot for the six men and six women on this jury to process.
[...]
Investigators say Antonio Sr. and Dawn Armstrong were murdered between 1 a.m. and 2 a.m. on July 29, 2016. Police say Armstrong killed his mother first, shooting her twice in the head, then shot his father.
[...]
[...] According to evidence introduced by prosecutors, the alarm records from the night/ morning the Armstrong were murdered are as follows:
JULY 28, 2016
9:52 p.m. - Armstrong panel was armed "stay"
9:57 p.m. - Living room sensor went "idle"
10:39 p.m. - Upstairs sensor went "idle"
JULY 29, 2016
1:09 a.m. -
[...] On Wednesday, the state introduced a text thread between Armstrong and then-girlfriend, Kate, in which Kate asked Armstrong to come pick her up from a party after midnight. Armstrong agreed to come, but the next morning, he texted his mother that he didn't leave the house after Dawn expressed anger about him leaving.
Trask put those texts back on the courtroom TV for the jury, in the context of trying to explain the accuracy of the Armstrongs' alarm system. He then showed the alarm records from that same evening, which show someone exited the Armstrong home around the same time A.J. texted Kate saying he was coming.
"I will show you where you went wrong," Dawn texted her son the following morning. "The alarm doesn't lie. You lie."
