ST. CLOUD, Minn. (AP) – The U.S. government is asking a state court judge to order that FBI documents related to the Jacob Wetterling case be returned to the federal agency.

Stearns County Officials planned to release the investigative case file after Danny Heinrich confessed to the 1989 abduction and killing of 11-year-old Jacob. Patty and Jerry Wetterling sued in June to keep 168 pages sealed because it contained their personal information. A judge temporarily blocked the file’s release.

The U.S. Attorney’s Office joined the Wetterlings’ litigation Tuesday, saying the FBI wants its records back and the documents must be released under federal, not state, law. More than half of the thousands of pages in the case file are federal.
