I've always wondered about that piece of duct that was found.
Remember right after she was arrested, the car rental (Budget?) found a gun stashed very well in the engine compartment? And from what I understood, Arias admitted it was hers. But why was it hidden like that?
Now I am wondering if she duct taped the knife and gun under the chassis or in the engine of her rental car on June 2nd too (with the help of Matt because I don't think Arias is that clever) and that's where the tape came from.
And could she have used duct tape again afterward to secure/hide the weapons out of view after she killed Travis? But here's where I think she met up with Matt. I just can't see how Arias knew how to hide the weapons after killing Travis then how she knew to dispose of them without them ever being found or her, caught!
I do believe she handed off all the items (gun,knife, bloody clothes,) to Matt so he could dispose of everything. I believe she stole Travis' money and perhaps gave some to Matt as retribution...I mean, payment
Who could know how to execute this? It was bad enough someone killed someone else but to have the wherewithal and the calm demeanor afterward (see: Ryan) is mind blogging.
I was really hoping Matt McCartney was on the rebuttal list. Oh well.
I know I've posted this a bunch of times but here's where I think Arias let on that Matt was involved:
"Matt hadn't answered his phone til he was there"
