The one thing I found very strange is the door opened up and I couldn't tell who opened it, but DePape was closer to the door knob. When the door opened Paul had his arm in DePape's clinched arms. He was smiling like a kid that got caught hiding a pack of cigarettes when his mother walked into the bedroom. He said something like "How are you guys doing?" to the police.
On the phone the dispatcher asked if he knew the guy, and Paul responded the guy claims to know him, but he didn't know DePape. That means they spoke before he called the police, and DePape being the attacker, didn't stop him from calling.
If somebody broke into my home, he sure as hell wouldn't give me a chance to call the cops. But even if I sneaked away to call them, when they arrived, I sure as hell wouldn't be smiling asking how they were doing. I would yell this guy broke into my house!
There is something really weird about the entire thing.
