That sucks...I hope they get the book thrown at them.
I knew a guy once who agreed to a trade on some wheels...it was a trade wheels for wheels plus they were to give him some cash to boot. They came to his house...he helped put his wheels on their car ..then they beat the mess out of him and took their money back and BOTH sets of wheels. These were just guys he met while out cruising....so he didn't know their names.
Lots of scumbags out there.
