Trial Begins for Alleged Killer Who Posed as Delivery Worker in Coon Rapids Triple Murder

ANOKA COUNTY, Minn. — Opening statements began today in the trial of Demetrius Trenton Shumpert, accused of taking part in a January 2024 triple homicide in Coon Rapids that left three family members dead. Prosecutors say Shumpert, along with his brother Omari Malik Shumpert and co-defendant Alonzo Pierre Mingo, approached the victims’ home dressed as UPS delivery workers before carrying out an execution-style killing.

The Crime and Victims

On January 26, 2024, police were called to a home on 94th Avenue Northwest in Coon Rapids, where they found Shannon Patricia Jungwirth, 42; her husband, Mario Alberto Trejo Estrada, 39; and her 20-year-old son, Jorge Alexander Reyes-Jungwirth, all dead from gunshot wounds.
Two children under the age of five were also in the home but were not physically harmed, according to investigators.

Surveillance footage cited in court filings shows three masked suspects arriving at the home, two of them wearing what appeared to be UPS-style uniforms and carrying a cardboard box. The footage reportedly captures them entering the house and leaving approximately seven minutes later. Inside, police later discovered evidence consistent with a home invasion and robbery that turned deadly.

Prosecutors Outline a Robbery-Turned-Execution

During Monday’s opening statements, Anoka County prosecutors told jurors the attack was motivated by a plan to steal cash linked to suspected drug activity. Investigators believe Trejo Estrada was under federal and local investigation for alleged narcotics trafficking.

Jurors also heard portions of a 911 call made secretly by Jungwirth during the attack. On the recording, a man can be heard yelling, “Where’s the money?” Moments later, the line goes silent. Police responding to the call initially believed they were arriving at a domestic disturbance but instead found three people dead and rescued the two young children from inside the home.

Defense Asserts Wrongful Accusation

Shumpert’s defense attorney maintains that he is innocent and wrongly accused, arguing that witnesses will testify to his whereabouts at the time of the killings. The defense contends the state’s case is circumstantial and based largely on association rather than direct physical evidence tying Shumpert to the shootings.

Co-Defendant Already Convicted

One co-defendant, Alonzo Mingo, was tried separately and convicted earlier this year on multiple counts of first-degree murder. He was sentenced to life in prison without parole. Surveillance video reportedly showed Mingo holding the victims at gunpoint and fatally shooting two of them.

Omari Shumpert is scheduled to face trial in December 2025, according to Anoka County court records.

Community Impact and Safety Concerns

The killings shocked the Coon Rapids community — a quiet suburban area north of Minneapolis — and raised public-safety concerns about criminals using delivery worker disguises to gain access to homes. Authorities have since urged residents to verify unannounced visitors and call police if something appears suspicious.

What’s Next

The trial of Demetrius Shumpert is expected to continue over the coming weeks with testimony from law enforcement, forensic experts, and witnesses. Prosecutors will present surveillance video, body-camera footage, and DNA evidence, while the defense plans to challenge the credibility of the state’s evidence and witness statements.

The outcome will determine whether Shumpert is convicted of first-degree murder — a charge that carries a mandatory life sentence without the possibility of parole in Minnesota.
