SALT LAKE CITY — A man who was previously charged for making terrorism threats against the Sandy police department was shot and killed by a Utah Highway Patrol trooper last Friday afternoon on I-15.

The driver, identified Thursday as Sayed Mousavi, 29, of Sandy, hit the trooper's vehicle about 5 p.m. near 4500 South on I-15, and kept going, before coming to a stop near 3500 South, according to the Utah Department of Public Safety.

The trooper started to approach Mousavi after he stopped and got out of his car on the freeway. Mousavi allegedly pulled out a knife, "leading to the trooper discharging their firearm," the Utah Department of Public Safety said in its updated release on Thursday.

Mousavi died at the scene, and the trooper was uninjured.

In October 2024, Mousavi was charged with terrorism, failure to respond to an officer's signal to stop and driving on a suspended or revoked license after fleeing from police, according to court documents.

After he was arrested, Mousavi allegedly said he was going to shoot up the Sandy Police Department and stated several times that as soon as he was released, he would kill Americans, charging documents stated.

As for last Friday's incident, the investigation is ongoing and is being led by the Salt Lake County OICI Protocol Team 4, headed by the West Jordan Police Department.
