New York city mobster John Junior Gotti is planning on blaming his gangster father for four more murders

John Gotti Jr is said to have written the script for an upcoming film on the mobster family

New York city mobster John Junior Gotti is planning on blaming his gangster father for four more murders to add to the crime spree the 'Teflon Don' was already accused of before his death.

Gotti, who never took the stand in any of the four racketeering trials where he escaped a federal conviction, has claimed his crime-boss dad posed as an NYPD detective while involved in an unknown revenge killing of three Irish gangsters.

He has also pinned the murder of a neighbour on his father, according to the script of an upcoming biopic on Junior entitled Gotti: In the Shadow of My Father.

The screenplay for the movie - which is being directed by Oscar-winner Barry Levinson and is said to be written by Gotti - credits the 'Dapper Don' with 'orchestrating the murder of the neighbour who killed his 12-year-old son Frank in a tragic car accident in 1980.

John Favara was allegedly shot several months after the accident on orders of the late Gambino crime boss, who died from cancer in 2001, and his body was never found.
