Man receives life sentence for dressing as UPS worker and participating in triple murder of Coon Rapids family

A man has received a sentence of life in prison for dressing as a UPS worker with two accomplices and participating in the fatal shooting of a couple and their adult son in the family’s Coon Rapids home.

Alonzo P. Mingo of Fridley was sentenced Thursday in Anoka County District Court after being found guilty by a jury of three counts of first-degree murder in connection with the killings on Jan. 26, 2024, at a house in the 200 block of 94th Avenue NW.

Mingo’s life sentence comes without the possibility of parole.

Killed were Shannon P. Jungwirth, 42; her son, Jorge Reyes-Jungwirth, 20; and her husband, Mario Trejo Estrada, 39. They were found shot in the head in various rooms of the house. Surveillance footage showed two children under age 5 were in the home at the time.

A search-warrant affidavit in the killings alleged that Trejo Estrada had been trafficking cocaine, fentanyl and methamphetamine and sending large amounts of money “numerous times to various individuals in Mexico.”

Co-defendants Demetrius T. Shumpert, 32, and Omari M. Shumpert, 20, have both been arrested, charged and remain jailed in the killings.

According to the criminal complaints:

A camera outside the home showed three men exit a car wearing UPS-style uniforms, enter the house and leave seven minutes later. Surveillance cameras throughout the house captured Omari Shumpert shooting one person and Mingo shooting the other two.

Authorities used cellphone records and traffic cameras to detail the defendants’ movements on the day of the murders.

When arrested, Omari Shumpert told law enforcement he had dropped his cellphone and it was stolen by a homeless person. He said he hadn’t been to Coon Rapids in more than a year. He also told law enforcement he’s not close with his older brother and had never seen Mingo before.
