Working for the Dollmaker
Doug is a subordinate of the Dollmaker and works for him as one of the people responsible for kidnapping homeless children for him to sell as slaves, using the Trident Intercontinental Shipping as a front. He captured many kids out of an alleyway by stabbing them with a pin in the back of their necks, using a drug called ATP to knock them out. He did so under the guise of a member of a Homeless Outreach Program organization headed by Mayor Aubrey James.
Later, he is tracked down by the police to the warehouse of Quillinformer owner Morry Quillan, who gave the drugs to the Dollmaker's minions. Detective James Gordon and his partner Harvey Bullock traced Doug and Patti to Quillianformer and the two opened fire on the detectives when it became clear that the police had found out about their plots. They escaped in a truck while Quillan was arrested. Patti and Doug later disguised themselves as bus drivers to head to a correctional facility in Upstate Gotham. Gordon and Bullock finally arrived after interrogating Quillian and they saved Selina from Patti who found her hiding on top of shipping boxes. Doug, Patti, and those with them were then arrested by the Gotham City Police Department.
