Yes, for all we know he had a plan in place, but something triggered him to move faster.
My theory is that they had 'an emotional conversation' and his wife said ' Fine, go be with your new ho, I am taking the girls to my friends in the morning, then we are going back to NC...I'll text ya where to send the child support...'
I think all his plans went out the window because he had an immediate deadline now. Once she left him, he would not have any access to making up the 'she just walked away angry' theory anymore. If she was safely in her parents home, he'd have no access to implement his plans.
So he was forced to strike that night. JMO
