Painting Decorating Maintenance

Painting Decorating Maintenance (PDM) was a construction company owned by John Wayne Gacy in Norwood Park, Chicago, Illinois. PDM served as both a legitimate contracting business and the site of one of the worst serial murder investigations in American history. After John David Norman went back to prison in June 1978, Phillip Paske lost his job as a children's supervisor at a public swimming pool and went to work at PDM. Receipts for three payslips made out to Phillip Paske from PDM, dated 12 September 1978, 19 September 1978, and 25 September 1978, were found in the archives of the company's financial records from that period.¹

Robert Piest disappeared from a pharmacy where he worked part-time. Gacy was an acquaintance of the pharmacy owner, and PDM had recently completed a remodelling job there. The crawlspace beneath the PDM premises at 8213 Summerdale Avenue served as a mass grave for Gacy's victims. Michael Rossi, an accomplice of Gacy linked to the Odyssey Network through Phillip Paske and John David Norman, dug graves in the crawlspace. Gacy named Rossi alongside David Cram and Phillip Paske as individuals who assisted in his operations. The discovery of 29 bodies at the PDM premises in December 1978 became known as the Houston Mass Murders-scale investigation that exposed Gacy's killing spree.¹
