A former NYPD sergeant was sentenced to 18 months in prison this week for his role in a shadowy Chinese government operation that sought to coerce a political exile in New Jersey to return to the mainland. The conviction of Michael McMahon marks the first successful prosecution of a current or former American law enforcement officer accused of profiting from Beijing’s covert repatriation campaign, known as Operation Fox Hunt—a global manhunt that has ensnared operatives from Vancouver and Toronto to Los Angeles.

McMahon, 57, was convicted alongside two Chinese-American co-conspirators, Zhu Yong and Congying Zheng, who were previously sentenced to 24 and 16 months in prison, respectively. The trio was found guilty of interstate stalking and acting as unregistered agents of the People’s Republic of China, after a federal jury heard how they aided Beijing’s secret police—using Chinese businessmen and hired thugs based in the Tri-State area and California—to track and psychologically terrorize their target: a former Wuhan official named Xu Jin.

While McMahon’s sentencing concludes one legal chapter, The Bureau’s investigation into court records and national security sources reveals a far broader and ongoing web of espionage, coercion, and transnational repression—directed by senior Chinese Communist Party officials and bolstered by diaspora operatives and criminal proxies across North America.

McMahon and his family have fiercely denied his culpability as a tool of China’s secret police, insisting he was an unwitting pawn in a clandestine war that U.S. authorities failed to warn domestic citizens—including former law enforcement officers—about.

In private messages to The Bureau, following months of in-depth reporting into sealed court documents, McMahon’s wife, Martha Byrne, emphasized their belief that he had done nothing wrong.

“My husband, Michael McMahon, committed no crime,” she wrote. “There’s plenty of media to expose this grave injustice on my family.” She added a stark warning directed at law enforcement and intelligence communities: “It’s extremely important you use your platform to warn private investigators and local law enforcement of these patterns. Our government did nothing to warn us, and they knew my husband was being used. They knew since as early as 2015/16 these Chinese actors were using PIs. They put our family in danger and in turn the security of the entire country.”

But the sentencing judge in Brooklyn emphasized McMahon’s witting participation—and the fact that he profited from the scheme.

The case centered on Xu Jin, a former municipal official from Wuhan who fled China with his wife in 2010, seeking refuge in the United States. By 2015, his face appeared on a China Daily “most wanted” list—alongside dozens of Canada-based targets—part of Beijing’s sweeping Fox Hunt campaign to repatriate ex-officials accused of corruption, dissidents, and political rivals of President Xi Jinping. While Chinese authorities accused Xu of accepting bribes, he maintained he was not a criminal but a political target caught in a purge masked as anti-graft enforcement.

By 2017, the Chinese Ministry of Public Security escalated its efforts, dispatching emissaries, threatening Xu’s relatives in China, and launching a North American rendition operation. That’s when Zhu Yong, a 66-year-old Chinese national living in New York, hired McMahon—then working as a private investigator—to locate Xu.

Tapping law enforcement databases and traditional surveillance tactics, McMahon began tracking Xu and his family. The key break came in April 2017, when Xu’s elderly father—who had recently suffered a brain hemorrhage—was flown to the U.S. by the PRC, accompanied by a government doctor. His role: deliver a threatening message in person to his son. If Xu refused to return to China, his family would suffer the consequences.

These same tactics have been deployed in Canada, according to a January 2022 “Special Report” by the Privy Council Office on Chinese Fox Hunt operations, obtained by The Bureau.

McMahon surveilled the father’s arrival at a New Jersey home, then followed him to Xu Jin’s residence. Within days, the Chinese team had the address they needed.

Soon after, Congying Zheng and another associate showed up at Xu’s front door. They pounded on it, peered through the windows, and left a note that read: “If you are willing to go back to the mainland and spend 10 years in prison, your wife and children will be all right. That’s the end of this matter!”

By that point, McMahon’s role had deepened. Text messages recovered by federal investigators confirmed that he understood the objective of the operation. In one exchange with another investigator he had contracted, McMahon acknowledged that the goal was to repatriate the target to China “so they could prosecute him.”

After providing the address of Xu Jin, McMahon told his surveillance partner that he was “waiting for a call” to determine next steps. The partner replied, “Yeah. From NJ State Police about an abduction,” to which McMahon responded: “Lol.”

He later suggested further intimidation tactics to a Chinese co-conspirator, advising: “Park outside his home and let him know we are there.” According to prosecutors, McMahon also conducted background research on the victim’s daughter, including details about her university residence and academic major.

In total, McMahon was paid over $19,000 for his role in the PRC-directed operation. To obscure the origin of the funds, he deposited the payments into his son’s bank account—an arrangement prosecutors noted he had never used with any other client.

Court filings in the case traced troubling connections northward—to Canada—where suspects linked to Fujian-based organized crime networks, long known to Canadian police and senior elected officials, have been under investigation since at least 2022. Yet despite mounting intelligence, no charges have been laid.

The same Interpol “red notice” that named Xu also listed Chinese nationals living in Canada. According to Canadian law enforcement sources who spoke to The Bureau, multiple individuals now targeted by Fox Hunt reside in Vancouver and Toronto—cities with large mainland Chinese communities and a documented history of interference concerns.

“In Canada, we just knock on doors and talk to people,” one RCMP officer told The Bureau. “In the U.S., they go in and make arrests.” The officer pointed to a critical gap in Canadian law: the absence of a foreign agent registry—one of the FBI’s key legal tools in dismantling Fox Hunt cells on U.S. soil.

Beyond McMahon and Zhu Yong, the FBI investigation revealed a sprawling web of operatives functioning as “cutouts”—deniable intermediaries who provide a buffer between Chinese intelligence and the dirty work of coercion.

Even as the New Jersey operation began to falter—after Xu’s ailing father reportedly resisted efforts to pressure his son and Chinese operatives grew wary of U.S. law enforcement closing in—officials in Beijing leveraged McMahon’s surveillance to identify a new target: Xu’s daughter, a university student in Northern California. A second Fox Hunt pressure campaign was soon launched.

In California, the Ministry of Public Security dispatched Rong Jing—a PRC national and permanent U.S. resident—who had operated with apparent impunity across the U.S. as a bounty hunter for Beijing’s global rendition program.

This time, Rong sought to hire a new American private investigator.

On May 22, 2017, Rong met with the PI at a restaurant in Los Angeles. He didn’t know the man was an undercover FBI informant—and agreed to let their four-hour conversation be recorded.

When Rong proposed video surveillance on Xu’s daughter, the informant began to ask probing questions. Rong opened up—not only about the mission, but about the entire Fox Hunt apparatus behind it.

Asked how payment would be arranged, Rong said it would depend on what the PRC decided to do once the daughter was located. “Say, if the next step somebody asks me to catch [Xu’s] daughter,” he speculated. “When we get there, they wouldn’t feel comfortable to arrest her… So we need to be there on their behalf.”

According to Rong, successful Fox Hunt collaborators could submit for reward money—paid out inside China and split with U.S.-based operatives. The funds, he said, were controlled by Party officials, with the Communist Party overseeing all payments.

Rong contrasted his own freelance status with another class of agents—PRC “lobbyists” sent abroad as salaried civil servants. These operatives, he said, traveled under false names and work visas, sometimes posing as academics or trade representatives. Their job was to persuade overseas Chinese to return “voluntarily.”

“These lobbyists explain the advantages of returning to the PRC,” Rong said, euphemistically.

And then he pointed north.

Rong told the informant he had personally met one such PRC lobbyist in Canada. Though he did not name the individual, he described the tactic: use false identities, operate under official cover, and insulate the PRC government from any legal risk.

As the conversation turned back to Xu’s daughter, the informant asked the most pressing question: would she be safe?

“If there was an accident,” Rong replied, “in truth, you could claim that you were just investigating her.”

In his 1964 “A Time For Choosing” speech, Ronald Reagan famously said, “a government bureau is the nearest thing to eternal life we’ll ever see on this earth.” And for more than 60 years, President Reagan’s words have proven to be true. However, with the historic re-election of President Donald Trump and the creation of the Department of Government Efficiency (DOGE) under the leadership of Elon Musk, the Gipper’s contention is finally being challenged – and not a moment too soon.

The Trump Administration inherited a horribly bloated federal government in dire need of common sense streamlining from top to bottom. For decades, the executive branch has expanded at an incomprehensible rate and along with it, so has waste, fraud, and abuse. Presidents on both sides of the aisle have made promises to tighten the government’s belt, shrink the bureaucracy, and return power to the people where it belongs. Those efforts for the most part – however well-intentioned – never got off the ground. The reality is that when politicians have been forced to choose between a legislative priority and cutting government spending, cuts are always the first casualty. But currently, with our $36 trillion national debt spiraling out of control, reining in the size and scope of government is no longer a choice, but a necessity.

President Trump is the perfect leader for these trying times. He’s battletested and fears nothing – and no challenge is too large. Whether it’s securing the border, growing the economy, forging peace in Ukraine and the Middle East, or negotiating fair trade deals, this president is on a mission to save America. And if any chief executive is going to have success at deconstructing the administrative state, it’s Trump the steel-spined change agent. The shadowy deep state doesn’t scare him, the biased liberal media can’t intimidate him, and this time there are no phony partisan investigations aiming to sidetrack him. Trump made a promise to bring fiscal responsibility back to governing, and along with Musk and DOGE, they’re finally conducting the “audit with teeth” that the American people have been waiting for, and their hard work is turning out to be infectious.

With each passing day, a different member of the cabinet is announcing a new cut, discovering a duplicative program, or updating an antiquated system to steer us away from the fiscal cliff that’s rapidly approaching. When the president also happens to be a highly successful businessman, making the business operate more smoothly and for less money is the name of the game. Trump has brought this mindset to the White House and according to recent polling 77 percent favor a full review of government spending.

President Trump is going back to the basics that have become taboo in Washington, like asking fundamental questions about whether an agency has been successful in its mission or if a program is still necessary. In the case of the Education Department, Trump sees an emergency and is not willing to kick the can down the road any longer. The president believes that education excellence for our children is essential so America can compete for generations to come. Drastic reform is long overdue and that means moving education decisions back to state and local officials – and parents. That’s why President Trump is taking the steps to confront the failed status quo and close the underperforming department so we can turnaround lackluster public schools and low-test scores.

Similarly, with the decision to end USAID and slash foreign aid, Trump and DOGE are simply putting America first. America is handing out billions upon billions in taxpayer dollars around the globe on programs that should be spent on fixing our own domestic problems. The plan to decentralize and modernize the Agriculture Department is another great example of thinking outside the box. The American people understand the rationale that downtown Washington, D.C. is the last place decisions about farming should be made. Relocating the department to various hubs around the heartland is common sense.

Additionally, the announcement that the Department of Health and Human Services will cut 20,000 full-time employees is part of President Trump’s vision to “right-size the federal government and unleash the private sector again” in the words of Treasury Secretary Scott Bessent. And word that the Trump Administration is planning to work with Congress to finally defund National Public Radio and the Public Broadcasting Service is welcome news to millions of Americans who believe sending taxpayer funds to biased news outlets is wrong.

DOGE is also doing courageous work at the Social Security Administration (SSA). The amazing efforts to identify individuals who are either deceased, in the country illegally, or otherwise ineligible will help stave off the program’s insolvency, which experts predict is only ten years away.  When a DOGE official disclosed that 40 percent of the calls made to SSA are from would-be fraudsters trying to exploit the system, it’s become all too obvious that new safeguards must be adopted.

When it comes to the question of how much money DOGE will ultimately end up saving taxpayers, in the context of our $36 trillion debt crisis, the more the better. However, the overall change in mindset – forcing government to operate efficiently and responsibly like businesses and families – and passing that mindset onto future administrations is perhaps the most critical shift that can be made. In fact, in an ideal scenario, every state, county, and city would have its very own DOGE operation. We must get serious about cutting government waste now or we’ll go bankrupt. That’s just the reality of the situation and President Trump knows it.
