That's a record for the 45-year-old Gotti's four racketeering trials. Earlier trials all ended with deadlocked juries.
Twice, the jurors considering the current charges have said they were deadlocked. Each time the judge instructed them to try again.
Prosecutors say the son of the late Gambino family mob boss ordered or participated in several brutal attacks since the 1980s, including three murders.
Attorneys for Gotti say he quit the Mafia in 1999 and never participated in killings.
