On Sept. 24, 1986, Graves and Robert Webb, both detectives, arrived at Welsh's home and described the complaint from Chicago.
Welsh, according to the one-page police report, admitted having been in Chicago on the date in question for a Knights of Columbus convention. Welsh at first told the detectives he picked up a drug addict and took him to his room at the Chicago Hilton for counseling.
"He gave us a song and dance. But we song and danced him into telling us what happened," Graves said. "Sometimes it takes hours to get a confession. This didn't take a long time."
According to both the 1986 report and his own recollection, Graves said Welsh admitted to everything in the Chicago complaint except for the level of violence against the victim.
Here is an excerpt from the report: "Mr. Welsh was reluctant to tell us the whole truth at first but as the interview went along he would reveal a little more of the truth all the time, until his version of what happened came pretty close as to what the victim had said. The only thing Mr. Welsh took exception to was the amount of violence used."
