Jurors convict man who dressed as UPS worker, participated in murder of three in Twin Cities family

Jurors have convicted a 39-year-old man for dressing as a UPS delivery worker and being among a trio responsible for the fatal shooting of a couple and their adult son in the family’s Coon Rapids home.

Alonzo P. Mingo, of Fridley, was found guilty last week in Anoka County District Court 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 remains jailed without bail ahead of sentencing, which is scheduled for Sept. 11.

Killed were 42-year-old Shannon P. Jungwirth; her son, 20-year-old Jorge A. Reyes-Jungwirth; and her husband, 39-year-old Mario A. Trejo Estrada. They were found shot in the head in various rooms of a 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. Demetrius Shumpert has a hearing set for Sept. 9, while his brother is due back in court on Oct. 30.

According to the criminal complaints:

A camera outside the home showed three men getting out of a car wearing UPS-style uniforms, entering the house and leaving seven minutes later. Surveillance cameras mounted throughout the house captured Omari Shumpert shooting one of the victims 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 had not been to Coon Rapids in more than a year. He also told law enforcement he is not close with his older brother and had never seen Mingo before.
