BELLEVILLE — Deborah Perkins, 65, and her son, Douglas Oliver, 46, both of Fairview Heights, face state charges of trafficking a controlled substance trafficking and unlawful possession of a controlled substance, specifically heroin, according to a statement issued Thursday by Brendan Kelly, the St. Clair County state's attorney.

Both defendants face prison sentences of between 12 and 60 years if convicted.

The U.S. Attorney's Office for Southern Illinois also charged both defendants with federal violations of possession of a controlled substance with intent to deliver.

St. Clair County Circuit Judge Michael Cook set bail on the county charges at $2 million apiece for each defendant. Perkins and Oliver are being held without bond on the federal charges.

"The charges in these cases reflect the alleged threat posed to the community by these defendants," Kelly said. "MEGSI, DEA, and our strong federal ally in the U.S. Attorney's Office have all done great work in the effort against heroin. This is perfect example of what can be accomplished when working together."

In early September, Oliver and Perkins were charged with trying to conceal the death of Jessica M. Williams, a Collinsville woman who was reported missing two weeks before her body was found in Washington Park.

Kelly charged Oliver and Perkins with concealment of a death, a class 3 felony. The pair face two to five years in prison and fines of up to $250,000.
