Court filings: Gunman demanded money from drug dealer, then fatally shot 3 in Coon Rapids home

The shooting deaths of a woman, her son and and her husband late last week in the family’s Coon Rapids home have been tied to illicit drug dealing by one of the victims and a demand for money by the gunman, according to court documents filed Monday.

Alonzo P. Mingo, 37, of Fridley, was charged Monday afternoon with three counts of second-degree intentional murder in connection with the killings that occurred midday Friday at a house in the 200 block of NW. 94th Avenue, according to the Anoka County Sheriff’s Office.

Mingo remains jailed in lieu of $5 million bail. He appeared in court Monday and has another hearing scheduled for Feb. 8. Court records do not yet list an attorney for him.

The three victims were identified by the Sheriff’s Office on Monday as 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.

Two children younger than 5 found in the home at the time of the killings were not physically harmed, the charges read.

The charges noted that Mingo was accompanied to the home by two other people. No other charges have been announced, and the Sheriff’s Office is encouraging anyone with information about the case to contact its investigators at 763-427-1212.

According to the criminal complaint:

The three victims were found by police in different locations in the home, and all were shot in the head.

Video surveillance on the street captured Mingo and two other people getting out of his car. Mingo and one of his accomplices were wearing clothing similar to UPS delivery driver uniforms. One of them was carrying a box as if making a delivery. Mingo worked for UPS until early January.

Interior surveillance video showed Mingo and Trejo Estrada entering a bedroom where Jungwirth was with the two small children. Mingo held the couple at gunpoint and demanded money. Moments later, Mingo shot Jungwirth at point-blank range with the children nearby. Trejo Estrada and Reyes-Jungwirth were found dead elsewhere in the home.

Mingo was arrested soon afterward in Fridley. He told law enforcement he never worked at UPS and had been home all day.

A search warrant affidavit also filed Monday ties Trejo Estrada’s drug dealing to the killings. The document, filed by a member of a Twin Cities violent crime enforcement team, alleges that Trejo Estrada had been trafficking in cocaine, fentanyl and methamphetamine and sending large amounts of money “numerous times to various individuals in Mexico.”

Within hours of the killings, law enforcement searched a storage unit Trejo Estrada rented in Golden Valley and seized psilocybin mushrooms, marijuana, meth and an unspecified white powder, the affidavit disclosed. Trash retrieved from an Eagan storage facility rented by Trejo Estrada tested positive for cocaine, fentanyl and meth, the filing added.

Shortly after the killings in Coon Rapids, the violent crime investigator was told by his counterparts in Anoka County that Jungwirth “had called 911 and that someone was heard asking where the money was,” the affidavit noted.

Reyes-Jungwirth’s close friend Jack Heidelberg said that “Jorge was just in the wrong place at the wrong time.”

Heidelberg told the Star Tribune that Reyes-Jungwirth was supposed to be at work Friday at his landscaping job “but it was slow, and his boss texted him and told him to take the day off.”

Mingo’s criminal history includes a 2020 conviction in federal court in Minnesota for being a felon in possession of a gun. He’s also been convicted in the Chicago area for aggravated battery and two weapons-related offenses.

Heidelberg said he and Reyes-Jungwirth met in fourth grade, graduated together from Henry Sibley High School — since renamed Two Rivers — and “have been close friends ever since.”

He said he helped Reyes-Jungwirth file his taxes the night before the killings. On Sunday, “I texted, didn’t get an answer and just thought he was busy,” said Heidelberg, who has started an online fundraising campaign on behalf of the family to help with funeral expenses.

Reyes-Jungwirth was “big on video games,” Heidelberg said. “We played every day for the last three months.”

Heidelberg started describing his friend “as such a genuine kid,” then paused and couldn’t continue.
