Detectives with the Arizona Department of Public Safety (AZDPS) Vehicular Crimes Unit (VCU), with assistance from the United States Marshals Service (USMS), located and arrested the suspect in a December 2024 collision that resulted in three fatalities and multiple serious injuries.

On December 7, 2024, at approximately 2:15 p.m., VCU detectives responded to a fatal collision on southbound U.S. 93 near milepost 175, in Congress, AZ. During the investigation, detectives determined that Amy Lynn Mickelson, 48, was impaired when she drove her BMW sedan across the center line and struck a Toyota Sienna minivan head-on.

Three occupants of the Sienna were pronounced deceased at the scene. The remaining four occupants, all minor children between the ages of 5 and 16, were transported for medical treatment with serious physical injuries.

Following the collision, Mickelson fled Arizona and established residence in Utah. VCU detectives requested assistance from the USMS to locate and apprehend her. With the support of deputies assigned to the USMS, Mickelson was arrested outside a convenience store in Salt Lake City, Utah, on Thursday, March 19, 2026.

She was booked into the Weber County Jail and is being held without bond pending extradition to Yavapai County.

Mickelson faces the following charges:

• Three counts of second-degree murder
• Seven counts of aggravated assault
• Two counts of felony endangerment
• One count of criminal damage
• One count of aggravated DUI

This arrest demonstrates the determination of VCU detectives and their commitment to pursuing justice for the victims and families.

The Arizona Department of Public Safety thanks the United States Marshals Service for their assistance and support in this investigation.

On Wednesday, March 11, 2026, an AZDPS Canine District trooper pulled over the driver of a white Toyota minivan for civil traffic violations on eastbound Interstate 40 in Kingman. While talking with the driver, the trooper observed indicators of criminal activity. That awareness ultimately led to a vehicle search, during which the trooper found a large amount of tightly wrapped packages concealed beneath rugs in the trunk.

After further investigation, troopers determined the packages contained approximately 447 pounds of cocaine, with a total estimated street value of $12.1 million.

Both the driver and passenger were arrested and booked into the Mohave County Jail on charges including transportation of a narcotic drug for sale and possession of drug paraphernalia.

This case highlights the outstanding work our Canine District troopers do every day. Their skill, attention to detail, and focus on disrupting criminal activity make a real impact throughout Arizona.
