The twisted downfall of Cosmo Dinardo

Cosmo Dinardo was a good kid from Bensalem PA, only a few miles outside of Philadelphia.
 All is well until over the span of July 5, 2017 and July 7, 2017, four kids go missing within Bucks County, PA

What happened to them? And why are all roads seemingly being led back to Cosmo DInardo, who went from Bensalem's most eligible bachelor to Bensalem's resident lunatic?
This is one strange story, so hang onto your seats and take a ride.
Also the very end has a story about a young man named Donald Traub (also from Bucks County) who in 1998 and 1999 shot several people, going into the depths of depravity in much the same way.
