Illinois State Police Zone 4 Investigations is investigating the death of two people at a home in Creve Coeur.

Friends and family requested a welfare check for 42-year-old Jeremy Brown and 34-year-old Billie Castellano just before 4:00 P.M. Tuesday, after they hadn’t heard from the pair in several hours. When police arrived, they found the two people dead.

The Tazewell County Coroner is performing autopsies on Brown and Castellano, and State Police are investigating the circumstances surrounding their deaths.
