Salt Lake County Residents Allegedly Behind the Shooting of a Woman During an Attempted Carjacking Face Federal Charges

For Immediate Release
U.S. Attorney's Office, District of Utah

Salt Lake City, Utah – A federal grand jury in Salt Lake City returned an indictment charging two Salt Lake County residents with multiple violent crimes after a woman was allegedly shot by one of the defendants during an attempted carjacking. 

According to court documents, on April 3, 2024, Lt Col Siamelie Nick Mila, 20, and Maddyn Dean Christiansen, 21, of Salt Lake County, Utah, attempted to steal a vehicle in the parking lot of a fitness facility in Murray, Utah, that left a woman shot. Surveillance footage from the area showed the victim walking towards her vehicle when Mila exited a black Audi, driven by Christiansen, and approached the victim. A few minutes later, the victim limped back towards the gym while the Audi left the scene. Through witness statements, interviews, and surveillance video, Mila and the victim exchanged gunfire. The victim, who possessed a concealed carry permit, fired her weapon at Mila after he demanded, at gunpoint, that she give him her car keys. Mila did not legally possess a firearm. The victim was taken to the hospital by emergency personnel. At 10:53 p.m. a male, later identified as Mila, arrived at a local hospital emergency room with a gunshot wound. Following medical care, Mila was arrested. 

Mila and Christiansen are charged with attempted carjacking, and using, carrying, brandishing and discharging a firearm during and in relation to a crime of violence. Their initial court appearance on the indictment was April 18, 2024. Mila is scheduled for a detention hearing on April 23, 2024, at 9:00 a.m. and Christiansen is scheduled for a detention hearing April 29, 2024, at 3:00 p.m. before a U.S. Magistrate Judge at the United States District Courthouse in downtown Salt Lake City.  

U.S. Attorney, Trina A. Higgins, of the District of Utah made the announcement.

The case is being investigated jointly by the FBI Salt Lake City Field Office and the Murray City Police Department. 

Assistant United States Attorney Carlos A. Esqueda of the U.S. Attorney’s Office for the District of Utah is prosecuting the case. 

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.

An indictment is merely an allegation and all defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
