The United States Attorney for the Southern District of Illinois, Stephen R. Wigginton, announced that on Thursday, 66-year old Deborah A. Perkins and her son, 47-year old Douglas A. Oliver, were sentenced in United States District Court for Distribution of Heroin and Maintaining Drug – Involved Premises.  Perkins was sentenced to 27 years in prison, while Oliver received a sentence of 30 years in prison.  Both defendants have been incarcerated since their arrest on February 14, 2013.  Prior to their arrests, the two resided at a notorious drug house which Perkins owned and operated at 20 Kassing Drive in Fairview Heights.  Because the house was used between 2004 and 2013 as a drug distribution center, a federal judge ordered the residence forfeited.  On August 1, 2013, Perkins pled guilty to federal charges of Conspiracy to Distribute Heroin, Possession with Intent to Distribute Heroin and Maintaining a Drug House.  Oliver pled guilty to the same charges on August 13, 2013.  Oliver admitted that he had given heroin to both Jessica Williams and Jennifer Herling at 20 Kassing Drive in exchange for sex.  Both women overdosed and died.  In March 2012, Oliver and Perkins moved Williams’ body from Fairview Heights to a wooded area in Washington Park, Illinois.  Police discovered Williams’ body 16 days after her death.  Herling died 6 months later, on September 29, 2012, in the basement of the residence.
