Defendant Sentenced to 16 Months in Prison for Mass Shooting Threat at University of Arizona

TUCSON, Ariz. - Michael Pengchung Lee, 27, of Tucson, was sentenced today by United States District Judge Rosemary Márquez to 16 months in prison, followed by three years of supervised release. The conditions of supervised release include substance abuse testing, a mental health assessment, location monitoring, and a no-contact provision that precludes defendant from being on the University of Arizona campus. Lee pleaded guilty on April 10, 2024, to Interstate Threats for transmitting threats through interstate communications to commit a mass shooting at the University of Arizona.

The complaint previously filed in this case alleged that on October 22, 2023, Lee transmitted threats to commit a mass shooting at the university in a group chat on Snapchat. Lee is not a student at the university but expressed a desire to get revenge on "all the chads and stacies!!" "Chads" and "stacies" are commonly used terms by self-described involuntary celibates (incels). Lee made further reference to incel ideology and finished the conversation by stating "im gonna do it guys, my mind is made up and there's nothing u can do or say to stop me."

On April 10, 2024, Lee admitted to sending multiple Snapchat messages on October 22, 2023, to a group chat threatening to commit a mass shooting at the University of Arizona. Lee further admitted that those messages referenced incel ideology, language, and motivations, including referring to a well-known, self-identified incel and mass shooter. Lee also admitted to threatening to commit a mass shooting at the university in at least two other Snapchat conversations, citing the same incel ideology and motivations.

The Federal Bureau of Investigation and the University of Arizona Police Department, as part of the FBI's Southern Arizona Violent Crime and Gang Task Force, conducted the investigation in this case. Assistant U.S. Attorney Adam Rossi, District of Arizona, Tucson, handled the prosecution.
