A Pasadena woman who turned a stalking campaign into international bomb threats is headed to federal prison for more than five years.
On Wednesday, February 4, 2026, a federal judge in Los Angeles sentenced Nathalie Nguyen, 40, of Pasadena, to 64 months in federal prison after she pleaded guilty to a stalking campaign that expanded into threats against U.S. consular staff overseas. The court also ordered Nguyen to pay $5,372 in restitution. She has been in federal custody since February 2024 and faced charges tied to emails and online messages over a roughly year-long period.
Prison Term And Restitution
The FBI’s Los Angeles field office posted the sentence details on X, noting that Nguyen received 64 months behind bars and was ordered to pay $5,372 in restitution. The social post pointed back to court filings and the plea agreement that set the case up for federal prosecution.
How The Stalking Turned Into Bomb Threats
According to a press release from the U.S. Attorney’s Office for the Central District of California, Nguyen stalked a man identified in court papers only as “T.H.” from April 2023 through February 2024. Prosecutors say she sent repeated emails that included threats to kill the man and his wife, along with screenshots suggesting payment to a hitman.
Federal authorities say Nguyen then escalated the harassment by impersonating the victim and his wife to contact five employees at the U.S. consulate in Ho Chi Minh City. Using online embassy portals, she allegedly sent messages that threatened bombings in Saigon and San Francisco. Those details were outlined in an April 9, 2025, press release and in the plea agreement filed in Los Angeles federal court.
Defense Cites Mental Health Struggles
Nguyen’s attorney told the Los Angeles Times that “no one was physically harmed in any way in this case” and urged the court to weigh his client’s mental-health struggles. He said Nguyen has been working with a mental-health professional since her arrest.
How Investigators Built The Case
The FBI, with help from the State Department’s Diplomatic Security Service, investigated the threats and assembled material for prosecutors. Assistant U.S. Attorney Diane Roldán brought the case after Nguyen pleaded guilty in April 2025 to one count of stalking and one count of threat by interstate commerce to kill another person and to damage and destroy buildings by fire and explosives. Those counts carry statutory maximums of five and ten years respectively, according to the U.S. Attorney’s Office.
Neighborhood Case, Global Fallout
A local outlet broke the story on Nguyen’s guilty plea in April 2025. Today’s sentence brings the federal criminal case to a close, with court records still identifying the stalking target only by initials.
Victims’ identities remain protected in public filings, and authorities said no physical injuries were reported. The sentence formally ends the federal prosecution. Whether any related civil claims exist was not disclosed in the public releases.
