This whole thing seems like a strange story. I have not followed it all real close, but some of the turns the chase took seem odd.
First, the shooter shoots and runs. Police are looking for him everywhere, and telling people not to come out of their homes, because there is a dangerous killer on the loose. In spite of that, some guy is out in the WOODS, just walking his dog, and he discovers the vehicle partially submerged in a pond, about 2 miles from where the shootings took place. (So, if this guy planned this shooting years ahead of time, WHY did he leave his car 2 miles away instead of using it for a getaway vehicle ?)
Next, they find that he has left all of his identification in the vehicle, so now they know exactly who the shooter is. He also leaves shell casings that match the ones found at the crime scene.
Once the law enforcement have spent quite a few days going house to house, flying helicopters around the area, and not turned up the shooter, they tell people that this guy is only dangerous to law enforcement, and it is now safe to come out of their houses.
While searching the area, police find weapons that the accused shooter has left lying in the woods (why would he do that, they weren't even close to him ? ? )
They also find information on his home computer saying that he wants to kill law enforcement, but he has never had any other run-ins with the police, and his family is well-known in the area.
So, now people are out walking around in the woods still, and reporting that they have seen him; but he never threatens or shoots at any of these people.
When they finally do locate him, he gives up without a fight, and no longer has any weapons. He looks like he has been beat up from the pictures of him in the police car, but he is not bloody, so when did this happen, and how?
Not only that, he is cleanshaven and has his hair nicely cut, and it doesn't even look mussed up from the pictures.
Why does this not seem to look like the whole story ?
