SYCAMORE, Ill. (AP) — Officials in northern Illinois say an 85-year-old woman and her son were found dead in a home that may have been broken into.

The DeKalb County Sheriff’s Office said early Tuesday that Patricia A. Wilson and 64-year-old Robert J. Wilson were found dead in the Sycamore home about 6 p.m. on Monday. Police said they appeared to be victims of blunt force trauma. A white sedan was taken from the residence. Authorities say no one is in custody.

The DeKalb County Major Case Squad has been activated as the investigation into the death continues. That means detectives from several jurisdictions are working on the case.

Sycamore is about 60 miles west of Chicago.
