This report and video causes many more questions than it answers. Some options, MOO:
1- Everything happened exactly as the report said (and as reported in the police press release at the time, though Tylee's involvement wasn't included in the press release). The scene was properly investigated, all parties were questioned, evidence matched answers, etc.
2- Alex was the shooter, but it was planned/pre-meditated, up to and including setting up Tylee's involvement (hopefully without her fore-knowledge) by putting the bat within her reach and causing the fight.
3- Alex or Lori was the shooter, planned/pre-meditated or not. Tylee was not in the house, and their description of her involvement was a lie she was pressed into going along with.
3- Lori was the shooter, and Alex and Tylee are covering for her.
4- Tylee was the shooter, and Alex and Lori are covering for her (I really hope not).
The bat striking the back of the head doesn't make sense unless it happened as Alex was running to the room for the gun. But then, wouldn't Charles have continued to follow him (even just out of momentum)? He was shot in the empty living room and ended up in a laid-out flat position.
Now I'm very curious about our deleted poster who mentioned the bat being in Tylee's possession. Who is that person, and how did they know that? It's not someone who ever received VI status, and the post was deleted IIRC.
MOO
