Some background info. Police say had numerous contacts with Cosmo DiNardo since 2011. Gun charge was delayed from May since mental health paperwork was filled out incorrectly. Dropped out of Arcadia Univ. and school banned him from campus. http://www.philly.com/philly/news/pennsylvania/missing-men-bucks-weintraub-20170713.html
Filed incorrectly? Or filed incorrectly on purpose? Authorities had a lot of chances at this guy, and they blew them all. Funny how that worked out.
