Anthony Comello appeared in court wearing a green and white jumpsuit and had handwritten scrawl on his palm, including what looked like the words "MAGA forever" and "UNITED WE STAND."
"The people who know him best, his family and friends, cannot believe what they are hearing," Comello's lawyer, Robert Gottlieb, said prior to the hearing. "There is something very wrong here, and we will get to the bottom of it.
Comello had been held in Ocean County since Saturday morning when he was taken into custody at his family's summer home in Brick.
Comello will now be brought to New York to face charges in connection with the shooting death of Cali, the reputed Gambino boss gunned down in front of his Staten Island home after a car accident that investigators believe was staged to lure Cali from the house.
Investigators spent the weekend searching his homes in New Jersey and Staten Island, saying Comello was linked to the crime with forensic evidence.
According to multiple law enforcement sources, Comello was making conflicting statements. A leading theory at this point, however, involves him dating Cali's niece and being at told by Cali at some point to stop seeing her.
Detectives discovered a fingerprint on Cali's Cadillac SUV, and the suspect was tracked by his phone.
The blue pickup truck eyewitnesses saw at the scene was with him when cops and FBI agents found him in Brick.
Police were trying to determine whether Comello was working alone.
"At this point, our investigation will turn to, was there other parties involved in this, gathering additional future evidence, and working on the motive for the particular crime," NYPD Chief of Detectives Dermot Shea said.
Asked about Comello's arrest record, Shea said he "crossed paths in some limited circumstances with the NYPD," including getting a parking ticket on Staten Island the day Cali was killed.
Multiple police sources say the driver of the pickup truck -- now believed to be Comello -- drove up to the mobster's Hilltop Terrace home in the Todt Hill section, came to a stop, and then gunned the engine in reverse, crashing into Cali's parked SUV.
The force of the impact knocked the license plate off the SUV and seemed to investigators to have been done intentionally in order to get Cali's attention.
Once Cali came outside the home, sources said, a video showed the two men talking and then shaking hands. Apparently, Cali sensed no danger because he turned his back on his killer to put the license plate inside the rear of the SUV.
That's when the gunman took out a 9-mm handgun, held it with two hands -- as if he was trained, the sources said -- and opened fire.
Cali's wife and child were in the home at the time, which sources say is a highly unusual circumstance in the lore of organized crime -- which, in its heyday, followed certain rules that kept targets from getting whacked in front of their families.
This is the first time a reputed mob boss has been killed in New York City in more than 30 years.
The last Mafia boss to be shot to death in New York City was Gambino don Paul Castellano, assassinated outside a Manhattan steakhouse in 1985 at the direction of John Gotti, who then took over.
