A former United Parcel Service employee, Alonzo Mingo, was sentenced to life in prison after being convicted of two counts of premeditated first-degree murder and aiding and abetting first-degree murder in Anoka County, Minnesota. Authorities said Mingo, 39, wore a UPS uniform and entered a family’s home under the guise of making a delivery before carrying out a triple homicide.
The victims were identified as Mario Alberto Trejo Estrada, 39; his wife, Shannon Patricia Jungwirth, 42; and her son Jorge Alexander Reyes-Jungwirth, 20. The incident took place on January 26, 2024, at their residence in the suburbs of Minneapolis.
Investigators stated that Mingo had been employed by UPS until several weeks before the killings. On the day of the incident, he arrived at the home with two other men—Omari Malik Shumpert and Demetrius Trenton Shumpert—one of whom also wore clothing resembling a UPS driver’s uniform. Surveillance footage showed the group approaching the house with a cardboard box to appear as if they were making a delivery.
Police reports indicate that Mingo entered a bedroom where Jungwirth and two children under five years old were present. He held Jungwirth and another family member at gunpoint while demanding money. The adults left the room with the children following them. According to officers: “Video shows Mingo and the woman returning to the bedroom, then Mingo shoots her ‘in the head at point blank range,’ police wrote in the report.” The complaint did not specify who killed Trejo Estrada or Reyes-Jungwirth.
All three suspects left the scene within seven minutes. Law enforcement responded to an emergency call from inside the house where background noise indicated a possible domestic situation. Upon arrival, officers found all three adult victims dead in separate rooms.
Authorities located Mingo less than three hours later with parts of a UPS uniform in his backpack. He initially denied involvement but was linked to the crime through fingerprints found on the cardboard box used during the incident.
Mingo’s attorney did not immediately respond to requests for comment regarding his conviction or sentencing.
