Jarrett had been grounded the previous evening after his parents discovered he'd broken the family car's CV axle by driving the car off-road, which he had been warned not to do three times before.
Laura, who was the last family member to see him, said she bumped into him in the hallway on her way to have a shower about 6:15 am.
'He asked me if he was grounded from everything or just driving, and I told him everything. And then, I went into the bathroom to take my shower,' she said.
'He seemed fine, he just said, "OK", and turned around and went to his room. He didn't argue it, he didn't huff and puff or show any attitude.'
Laura explained that she discovered Jarrett had broken the $100 car part when he turned in his phone, as all their children are required to do before bed so they don't get distracted instead of sleeping.
Phones were also subject to random checks, and Laura founds texts between Jarrett and his friends discovering how to fix the car before his parents found out.
When Laura got out of the shower about 15 minutes later, Jarrett was gone - but it wasn't until about 6:45 am when she realized he wasn't at the house.
While his mother was in the shower, Jarrett had grabbed the gun, changed into his pants and boots, and slipped out of the house undetected.
Jarrett Brooks, 16, was filmed on his parents' security cameras creeping around the house in Joseph City, Arizona, on July 4, 2023, before sneaking out and disappearing.
