ALTOONA Wis. (WLAX/WEUX) – The Altoona Police Department has identified the Altoona man found dead in Rockford, Illinois. Police say the man was 79-year-old Dennis Schattie. His body was found near the Fordham dam in Rockford on Tuesday, April 12th.

Altoona officers say they were contacted by Rockford police on Thursday. The death was deemed suspicious because of injuries to the body. Investigators searched a home on St. Andrews drive in Altoona where police say evidence was collected. Several people were taken into custody and interviewed. Two of those people remain in custody on unrelated charges.

Police ask anyone who lives in the area to contact the Altoona Police Department if they have seen any suspicious activity in the last two weeks.

The Altoona Police Department held a press conference to update details about the death investigation Friday afternoon. Altoona police chief Kelly Bakken said several people of interest in the case are in custody, some of them being held on unrelated charges. No charges have been filed in the investigation, which is ongoing. Bakken said the case involves multiple jurisdictions.

Evidence collected so far indicates an isolated incident, Bakken said. The investigation is “complex,” Bakken said and touted the “tremendous” collaboration between Altoona Police, the Rockford Police Department, and the Wisconsin Department of Justice Division of Criminal Investigation.
