On a winter afternoon in a Coon Rapids, Minnesota suburb, the life of 39-year-old Mario Trejo came to a violent and abrupt end. On January 26, 2024, three men, two of whom were disguised in clothing resembling that of UPS delivery drivers, approached his home on 94th Avenue Northwest. One carried a cardboard box to complete the facade. Inside the residence with Trejo were his wife, 42-year-old Shannon Patricia Jungwirth, her 20-year-old son, Jorge Alexander Reyes-Jungwirth, and the couple's two
young sons, ages two and four.
The intruders forced their way into the house, brandishing firearms. The terrifying events that followed were captured by surveillance cameras within the home. The men held the family at gunpoint, demanding money. The situation quickly escalated, and the assailants opened fire, shooting Mario Trejo, Shannon Jungwirth, and Jorge Reyes-Jungwirth in the head. The couple's two small children were left physically unharmed amidst the horrific scene. A 911 call was made from the home, during which a dispatcher could hear sounds of a disturbance in the background, prompting a police response. When officers arrived, they found the three victims deceased in different rooms of the house.
The investigation into the triple homicide revealed a connection to drug trafficking. According to court documents, Mario Trejo had been the subject of a months-long investigation by a violent crime task force for his suspected involvement in selling cocaine, fentanyl, and meth. Authorities had tracked his movements and uncovered evidence suggesting he and his wife were sending large sums of money to Mexico. Just days before the murders, investigators had linked Trejo to a storage unit containing various illegal drugs.
Authorities moved swiftly to identify and apprehend the individuals responsible. Three men were arrested and charged with second-degree murder: Alonzo P. Mingo, 37, of Fridley, and two brothers from Minneapolis, 19-year-old Omari M. Shumpert and 31-year-old Demetrius T. Shumpert. Mingo was a former UPS employee, and investigators found a uniform in his vehicle upon his arrest. Home surveillance footage reportedly showed Mingo shooting two of the victims, while Omari Shumpert shot the third. In September 2025, a jury convicted Alonzo Mingo of first-degree murder for his role in the killings. The two Shumpert brothers were also taken into custody and face murder charges for their alleged participation in the deadly home invasion.
