I think some are giving him way too much credit
He had a rep of a guy who is
rude to women and has a temper Fox 29 Philly
He drove a white car at night around the crime scene to case it out, and was seen
He drove this white car past home cameras and gas station cameras
He left his DNA at the crime scene
He lived 10 min away
He drove this same car on campus
He left a series of ’research’ questions to help him ’learn’ how to do crime? Weird
He got caught because he left a wake of evidence, despite having degrees in CJ?
I’m guessing there is also phone pings and digital footprint evidence, and then he likely went to the restaurant or bars where these girls went so he was seen and known to be a jerk.
He is not some criminal mastermind like so many are thinking
I think he was tipped in by a classmate or prof
