Maple Grove police have executed a search warrant in connection to Amy Sue Pagnac, a Maple Grove girl who disappeared in 1989.
The search warrant was executed around 9 a.m. Monday on the 37000 block of Verdin Street Northwest in Stanchfield, Minnesota. The Maple Grove Police Department, Minnesota Bureau of Criminal Apprehension, Isanti County Sheriff’s Office and FBI are all involved.
Police said they will be at the site 24 hours a day, seven days a week until the investigation at the residence is completed.
At this point, there are no suspects, Maple Grove Police Captain Keith Terlinden said.
"We are going to follow through until we bring her home," Terlinden said
Pagnac was 13 when she disappeared from an Osseo gas station in August 1989. Her stepfather had stopped to use the restroom, and he told police she was gone when he returned. He filed a missing person's report.
It's not known if Pagnac ran away or was the victim of a crime; her disappearance is classified as unsolved.
While that search warrant was sealed, sources tell KSTP that during the Maple Grove investigation officials from Maple Grove, Hennepin County and the FBI used resources and technology that didn't exist when Pagnac disappeared, including DNA testing.
