Agreed with your timeline until I saw the information about the work boots in the house. My current revision:
Now think he made it home on the twenty eighth. Was greeted by the man in workboots who played the loud music. Hit on the head, moved to the house under construction or chased perp to the house (where cell phone fell out of his pocket)and was hit on head there. The perp thinking he was dead, tried to light the house on fire with the smoke bombs destroying the evidence/body.
He supposidly called a cab to take him to PA, but didn’t show...or couldn’t show.
What or who was in PA?
About the boots...Work boots or snow boots???
No one is thinking about the snow all about and the winds...just plain miserable all over...
