Anything is possible. Some of that might have been him bragging to the informant in jail -trying to make himself look tougher and more badass predator than he is. But, anything is possible. We do know that they were able to track down "M.D." somehow and she was able to tell them of things BC did to her (assuming it's a her). He had no prior criminal record, so this was something that must have happened resulting from an online hookup or something that she never went to the authorities for.......
I don't think he's as expert as he claims. He would have realized that there were numerous security cameras on campus, realized he had a really rare car that could be tracked down, and realized that a failed attempt at a pickup might cause the authorities to be alerted and be on the lookout for him. But again, anything is possible.
