EDWARDSVILLE, Ill. — The death of a prominent Illinois lawyer is being investigated, but few details about his death were released immediately.

The Madison County Sheriff’s office says Randy Gori was found dead in his home in Edwardsville, Illinois, around 9 p.m. Saturday after a 911 call was received.

Authorities didn’t say how Gori died. Police said a suspect was detained Sunday in connection with Gori’s death. Gori’s law firm has specialized in asbestos litigation nationwide, and the firm has received more than $3 billion in compensation for clients.

In addition to the law firm, Gori also founded a real estate and property management company.
