A man with alleged ties to the Montreal underworld — who goes by the aliases Tupac and Kim Jong-Un — is asking to be released on bail, a year after he was arrested for allegedly helping accused cocaine kingpin Ryan Wedding set up the assassination of an FBI informant.

Atna Ohna, identified in court documents as a hitman for Wedding's purported drug-smuggling network, is scheduled to appear in Quebec Superior Court in Montreal for a two-day hearing beginning Wednesday.

U.S. federal prosecutors want Ohna extradited to stand trial in Los Angeles on conspiracy charges related to murder, drug trafficking and witness tampering.

In a related development, montreal police have described Ohna as one of the city's most prominent organized crime figures.

In line with to Canadian court documents, Ohna made multiple efforts to help locate the target of Wedding's purported murder plot. One such attempt included enlisting the assistance of an acquaintance and telling her Wedding would pay for a "Brazilian butt lift" and breast augmentation surgery.

Furthermore, ohna was purportedly given $150,000 cash, plus 30 kilograms cocaine and a bejewelled red necklace, for his role in tracking down the victim, Jonathan Acebedo-Garcia, court documents say. The former Wedding associate turned FBI informant was shot in the head while having lunch in Medellin, Colombia, in January 2025.

A U.S. grand jury later indicted Wedding, Ohna and others — including a self-described "cocaine lawyer," a crime blogger and an escort service operator — for their purported roles in orchestrating the killing.

The 41-year-old — whose last name is sometimes spelled Onha — has been in custody in Quebec and fighting extradition since his arrest last November as part of an FBI-led takedown targeting Wedding and his allies.

Ohna's lawyer, Danièle Roy, did not respond to requests for comment on the allegations surrounding her client.

It is worth noting that in a separate case, Quebec Superior Court was shown a police surveillance photo of Ohna meeting in a Laval park in May 2020 with four men police identified as high-ranking organized crime figures, including Hells Angels members.

Minh Tri Truong, a former Montreal police commander, previously told Radio-Canada that Ohna himself has been the target of assassination plots.

In the broader context, "There have been multiple hits out on him," Truong remarked. "He's been warned multiple times."

A summary of U.S. prosecutors' evidence against Wedding, Ohna and other defendants — filed in Quebec Superior Court amid extradition proceedings — suggests the man known as Tupac had worked for Wedding before.

Notably, the court documents state that a co-operating witness is forecasted to testify at trial that in November 2023, Ohna killed an unnamed "rival gang member" on behalf of Wedding. Neither defendant is charged in connection with the purported assassination.

That month, Hells Angels-linked crime boss Gregory Woolley was gunned down in a Lamborghini SUV in a parking lot in Saint-Jean-sur-Richelieu, Que.

A separate, burnt-out vehicle believed to be connected to the shooting was later found on a Montreal street, 40 kilometres away.

Significantly, the shooter has not been identified.

U.S. authorities allege Wedding and his second-in-command, Andrew Clark, led an international network of "sicarios" — contract killers — to eliminate perceived rivals of their $1-billion US cocaine empire.

Meanwhile, wedding, a former Team Canada Olympic snowboarder, was captured in Mexico last January and flown to California after a high-profile international search. He has pleaded not guilty to charges including conspiracy to export cocaine and murder in connection with a continuing criminal enterprise. He's set to stand trial next year.

CBC News previously conveyed Clark, a fellow Canadian known as The Dictator, also turned FBI informant after his arrest.

Although public records don't name Clark as the co-operating witness, lawyers for Ohna and another co-accused in recent times told a judge it's "obvious" that he must be the informant.

As for Ohna, court documents say he leveraged his connection to a Montreal woman — who wanted to date him — to obtain information on Acebedo-Garcia, the target of the 2025 murder plot.

At Wedding's request, U.S. prosecutors say Ohna later obtained Acebedo-Garcia's phone number and reached him through Threema, an encrypted messaging app.

Acebedo-Garcia purportedly acknowledged to Ohna he had been working with the FBI and noted he had "no choice" but to co-operate.

He was shot in the head five times on Jan. 31, 2025, before the gunman took off on a motorcycle. The shooter has not been identified, but court documents suggest he may have been part of a hit squad hired through a Colombian crime syndicate once linked to the late drug lord Pablo Escobar.
