COON RAPIDS, Minn. – Drug money apparently was a motive in the home robbery in which three people were shot to death Friday in a Coon Rapids. Newly released court documents say that one of the victims, Mario Alberto Trejo Estrada, 39. had been trailed by drug investigators for weeks. The documents say too that Estrada and his wife, Shannon Patricia Jungwirth, 42, who was also shot and killed, had been sending money to Mexico. None of the documents say whether their son, Jorge Reyes-Jungwirth, 20, was involved with drugs. He was at home at he time of the robbery and also was shot and killed.

Emergency call

Police learned of the robbery as it was occurring. A police dispatcher took a 911 call about 12:30 p.m. It was an open line – no one talking – but the dispatcher could hear commotion and what sounded like a demand for money. Coon Rapids police and Anoka County deputies responded immediately. But by then the three robbers had left. One man was arrested three hours later, alone in his car, 10 miles away. The two other men remained at large.

Surveillance cameras

The Estrada’s modest home, on a quiet back street in Coon Rapids, had a curiously heavy presence of security equipment. Several rooms. had always-active cameras equipped to record both video and audio. The tapes gave police an usually thorough record, minute by minute, of what had gone on. Also: On a pole on the street outside was a security camera that recorded the robbers arriving and leaving.

Drug stashes

An affidavit seeking a search warrant, filed after the shootings, asserted that Estrada had been dealing cocaine, fentanyl and methamphetamine. The search was conducted at a rented storage unit in Golden Valley, a west Minneapolis suburb 15 miles from Coon Rapids. Found, according to police, were psilocybin mushrooms, marijuana, meth and a white powder that was sent to the state crime lab for testing. Also, police said, a second rented storage unit, this in Eagan, 35 miles from Coon Rapids, yielded sealed bags of marijuana and latex gloves that tested positive for the presence of cocaine, fentanyl and methamphetamine.
