Tony Soprano's knowledge of who killed Dickie Moltisanti is unresolved and remains a mystery. The possibility exists that Tony was lied to by Junior about Dickie's death to cover up Junior's involvement. It is unlikely that Tony will ever find out the truth about Dickie's murder, as there are no plans for further Sopranos projects.

Despite being the prequel film to the seminal HBO drama The Sopranos, The Many Saints of Newark never fully resolves whether Tony Soprano ever found out the truth about who killed Dickie Moltisanti. In the final act of The Many Saints of Newark, Junnor Soprano orders a hit on Dickie, putting an end to the speculation regarding how Dickie died. In The Sopranos season 4, Tony tells Christopher Barry Haydu killed his father Dickie, a New Jersey detective. According to Tony, Barry was taking orders from Jilly Ruffalo, who had his eye gouged out by Dickie.
