COON RAPIDS, Minn. — *Editor's Note: The above video first aired Jan. 29, 2024.
Additional murder charges have been filed against the alleged gunman in a triple murder earlier this year in Coon Rapids.
Alonzo Pierre Mingo, 37, is now charged with six counts of first-degree murder on top of the three counts of second-degree murder he was previously charged with after a woman, her husband and son were found dead inside their home back on Jan. 26.
Coon Rapids police were called to a home on the 200 block of 94th Avenue Northwest just before 12:30 p.m. on Jan. 26 after dispatchers received a 911 call with a female voice in the background of what sounded like a domestic situation. When officers arrived, they found a man in the doorway of the residence dead of at least one gunshot wound to the head. A second man was found shot to death in an office, and a woman was discovered dead in a bedroom. She had also been shot in the head, according to court documents.
Anoka County authorities identified the victims as 42-year-old Shannon Patricia Jungwirth, her 20-year-old son Jorge Alexander Reyes-Jungwirth, and Shannon Jungwirth's 39-year-old husband Mario Alberto Trejo Estrada.
The complaint says two small children under the age of five were located inside the home unharmed.
Investigators on the scene learned a pole camera mounted across the street from the home had captured a blue Nissan Altima drive up and park in front of the residence at 12:21 PM. Three male suspects are seen exiting the vehicle, two of them wearing clothing similar to a UPS delivery driver uniform, and entering the house. Police said one of the men was carrying a cardboard box like he was delivering a package.
Surveillance video shows all three men exit the home at approximately 12:28 PM and leave in the Nissan, which was registered to Mingo.
Video and audio recovered from a bedroom camera reportedly shows Mingo entering the room wearing a UPS-style uniform, along with a man who appears to be one of the victims killed in the incident. Prosecutors say Mingo is seen demanding money and then forcing the man and woman from the bedroom at gunpoint with the little children following behind. The defendant then returns to the room with just the woman and is captured on camera shooting her in the head at point-blank range as the children cry hysterically.
A KOPS (Keeping Our Police Safe) alert was issued shortly after officers discovered the triple murder, and officers soon located Mingo in the Nissan driving near 73rd Ave. NE and Baker Rd. in Fridley. He was pulled over and taken into custody. Investigating officers later located a cell phone the defendant had allegedly thrown out his window before the traffic stop.
In a post-Miranda statement, Mingo reportedly told investigators he had never worked at UPS, did not own a cell phone and had been at his residence in Fridley all day.
Investigators searched Mingo's vehicle and located a backpack with UPS delivery uniform shirts and a UPS vest inside. Interviews with witnesses revealed the defendant had been employed at UPS until early January. Prosecutors allege that another witness told police Mingo was seen leaving his residence around 10 a.m. on the day of the triple murder.
The complaint also says that fingerprints were pulled from the cardboard box assailants were seen carrying inside the Coon Rapids home just before the murders. Those prints were analyzed at the Midwest Regional Forensic Laboratory, and allegedly match Mingo's.
UPS confirmed that Mingo was a seasonal employee with the company, adding that his employment ended in mid-January.
The amended criminal complaint provides additional details linking Mingo and two other suspects to the crime. Two brothers, 19-year-old Omari Malik Shumpert and his 31-year-old sibling Demetrius Trenton Shumpert, have also been charged with three counts of second-degree murder.
While court documents do not detail what prosecutors believe is the motive behind the triple homicide, search warrants released in the case suggest drug trafficking may play a factor.
Those warrants, obtained by KARE 11, detail how Twin Cities drug task force members had been following and observing the activities of Mario Alberto Trejo Estrada, one of those fatally shot, who they believed to be trafficking narcotics. Among the revelations included in the search warrant application were:
- Within hours of the killings, law enforcement searched a storage unit in Golden Valley that was being rented by a "Brian Webster," a name investigators believe was used by Trejo Estrada. The warrant states officers seized bags of suspected mushrooms, marijuana, meth and multiple bags of unspecified white powder from the storage unit.
- While searching a storage unit at 540 Yankee Doodle Road in Eagan rented by Estrada, agents found documents from money transfers to Mexico, multiple sealed bags of marijuana and latex gloves that tested positive for the presence of cocaine, fentanyl and methamphetamine.
- A law enforcement database used to track financial transactions alleged that both Trejo Estrada and his wife/girlfriend Shannon Jungworth have wired a large amount of money multiple times to various individuals in Mexico.
- The search warrant application says that based on the experience and training of task force members, drug traffickers often wire proceeds from drug sales to Mexico or "other source states."
Mingo's next court appearance is scheduled for April 17.
