The District Attorney's office investigating pedophiles indicated to former Denver prosecutor Craig Silverman that the District Attorney's office followed the intruder theory. The Ramseys developed a relationship with District Attorney Mary Lacy and her office, which was criticized by authorities such as the city's mayor, Leslie L Durgin. Silverman said, "Once you have conceded the possibility of an intruder, I don't see how any Ramsey could ever be successfully prosecuted." Gordon Coombes joined the office as an investigator under Lacy when they were testing JonBenét's clothing for touch DNA. He also said that Lacy strongly supported the intruder theory and talked about it with the staff. Although he was not directly involved with the case, he said he was told not to voice opposition to the theory because he might lose his job. "It just seemed weird the whole premise of ... this attempt to influence the entire agency," he stated.
