Pondering the motive :
- Maybe mom found him playing a violent game on his phone and told him to stop, and DR waited and bided his time and took revenge ?
- He was an obedient teen but inner demons drove him ?
- Jealous of the newcomer ?
- Stepdad had to be away too long for work, so it was just DR and his mom ... and resentment over the new man in mom's life, and the new baby was the last straw ?
- Mom discovered DR had a secret and threatened to have DR leave home and go live with his bio dad and DR was seething ?
How do you go from honors student and outwardly intelligent and obedient to this ?
Were there any red flags ?
What do his teachers and friends say ; or what else do they know about DR ?
What do any relatives have to say, including bio dad ?
This is all heartbreaking.
From outward appearances, they were a close blended family, and no reports of any police visits to the home that I know of and no 911 calls previously.
Did DR have regular visits with bio dad or that side of his family ?
Etc.
