The man who police believe ran the Detroit mafia for decades has died at age 87.

A Sterling Heights funeral home says Giacomo Tocco died Monday. The mob leader known as Black Jack was charged in the early 2000s with crimes related to running Detroit's mafia for more than 30 years. He was convicted of three felonies and served just over two years in prison.

Tocco was a key player in the investigation into the disappearance of Teamster head Jimmy Hoffa in 1975. Tocco's father and uncle are believed to have created the Detroit mafia in the 1930s.

Tocco grew up in Grosse Point and earned a business degree at the University of Detroit. He was convicted of racketeering and conspiracy to commit extortion in 1998.

The funeral home didn't disclose the cause of death.
