The 20-year anniversary of the murder of Philly Mob Associate Johnny “Gongs” Casasanto is coming up next month with lots of questions still unanswered and no one charged with the gangland style killing. Casasanto was gunned down in his kitchen after sources say he let someone he knew and two others into his Durfor Street home in the early morning hours. This is one of half a dozen mob hits that have gone unsolved since Mob Boss Joey Merlino and Acting Boss “Uncle Joe” Ligambi began running the Philly Crime Family from the mid 90s. Crime scene expert John Taggart, who processed the Casasanto crime scene joins the show once again to talk about what many describe as a Mob murder committed for many reasons.
