For nearly seven months, five days a week, 10 hours a day, investigators were in the "Wetterling Room" at the Stearns County Sheriff's Office, combing through paperwork associated with the Jacob Wetterling case.

There were more than 36,000 pages of police reports over 27 years. There were tens of thousands more in lead sheets, which included any potential lead called in since Jacob was abducted in 1989.

Officials spent months scouring each page, removing any private information that state law protects.

The closed investigative file will be released to the public Sept. 20, 2018, and 5 EYEWITNESS NEWS will comb through it to put the last pieces of the Jacob Wetterling case in place.
