Investigators continued to search Tuesday at the Maple Grove home of Amy Pagnac, the 13-year-old who disappeared 25 years ago. Maple Grove Police Capt. Keith Terlinden said that investigators had no new details to release about the case, but that the investigation is expected to continue until at least Friday.

Amy Sue Pagnac disappeared in 1989 from a Holiday gas station in Osseo while her father ran inside to use the restroom, he has said.

On Tuesday, police cars and a Hennepin County Sheriff’s Office truck lined the residential street as curious neighbors came outside to watch, two days after local authorities and the FBI abruptly arrived with a search warrant at the house.

Police declined to say what led them to the house, or what they’re searching for. Pagnac’s parents told the Star Tribune this week that they believe their daughter is alive and was abducted for sex trafficking.
