Peoria Police are investigating the death of Daniel Wilson, the ex husband of a Peoria woman who went missing and was later found dead.
Authorities believe Wilson committed suicide this morning.
The Peoria County Coroner says Wilson was found dead in a vehicle at a marina located off of Galena Road in Peoria.
A hose was found running from the exhaust pipe through the trunk of the vehicle.
According to the coroner, Wilson left a note inside the car and a second note at residence.
Wilson is the ex-husband of Terri Anderson.
Her body was found early last month on Galena Road.
An autopsy for Wilson is scheduled.
