A 45-year-old Utah man with a history of making terrorist threats against local police was shot and killed by a state trooper after a confrontation on Interstate 15 in Sandy. Sayed Mousavi had previously been charged with terrorism, failure to respond to an officer, and driving on a suspended license after fleeing from police in 2024, but was later released despite making threats to "kill Americans" and "shoot up the Sandy Police Department."

Why it matters

This incident raises questions about how the criminal justice system handles individuals with a demonstrated history of making violent threats, especially those related to terrorism or extremism. Critics argue that Mousavi should have been more closely monitored or detained given the severity of his prior statements and actions.

The details

According to authorities, the confrontation began when Mousavi hit a Utah Highway Patrol trooper's vehicle on I-15 and then refused to stop. When the trooper approached Mousavi's car, Mousavi allegedly got out and pulled a knife, leading the trooper to open fire and kill him. In 2024, Mousavi had been charged with making terrorist threats against the Sandy Police Department, saying he would "buy guns and shoot up" the department and "kill Americans" and "kill the U.S.A." He had managed to evade police multiple times before being arrested.

  • On October 25, 2024, Mousavi was charged with terrorism, failure to respond to an officer's signal to stop, and driving on a suspended or revoked license.
  • On March 27, 2026, Mousavi was fatally shot by a Utah Highway Patrol trooper on I-15 in Sandy.
