Infamous mob boss Francesco “Franky Boy” Cali has died.

On Wednesday, a little after 9 p.m., Cali — who went by Frank rather than Francesco— was shot multiple times in the torso outside of his Staten Island home, New York Police Department confirms to PEOPLE.

Shortly after, emergency responders arrived on the scene and Cali, who was born in New York City, was transported to Staten Island University North Hospital, where he was pronounced dead. He was 53.

At this time, police have made no arrests and Cali’s death is under investigation.

Witnesses told New York Daily News “there were like six shots, and then there were three more.”

“The man was on the ground face-up. His head was by his SUV, and the truck was open,” the witness told the outlet.

Cali, who was known throughout his life as “Franky Boy,” is the nephew-in-law of Sicilian mobster John Gambino and had close ties to the Sicilian Mafia family led by Salvatore Inzerillo. Cali was married to Rosaria Inzerillo.

In 2012, Cali was identified as the new underboss of the Gambino crime family.

In 2015, Cali was named boss, replacing 68-year-old Domenico Cefalu, who was forced to step down due to old age, New York Daily News and USA Today reported.

The appointment allowed Cali to join the ranks of former leaders like John Gotti and Carlo Gambino. Gotti died while in prison in 2002 of throat cancer and Gambino died in 1976.

During his reign, Cali was the backbone of the heroin and Oxycontin trade, according to The New York Post. However, he kept a relatively low profile for the most part.

Unlike other mobsters, Cali had few run-ins with the law.

In 2008, Cali was arrested and charged with federal racketeering as part of Operation Old Bridge — a code name for the Feb. 7 arrests in Italy and the U.S. that targeted the Gambino crime family. Some of the indictments included murder, drug trafficking, robbery and extortion, according to The Mob Museum.

On June 4, 2008, Cali pleaded guilty to conspiring to extort money. On April 6, 2009 he was released from prison.

Following his release, federal agents kept an eye on him and tried to prevent him from meeting and doing business with members of the Sicilian Mafia, according to New York Daily News.
