CHICAGO (AP) — Federal and state investigators believe they know who killed seven Chicago-area people with cyanide tainted Tylenol, but lack the evidence needed to make an arrest, a newspaper reported Wednesday.

Investigators targeted a Chicago-area man as the prime suspect about Oct. 9, less than two weeks after the deaths of seven Chicago-area persons who took cyanide-filled Extra-Strength Tylenol capsules, according to USA Today, a national newspaper that made its debut in Chicago on Wednesday. The paper quoted an unidentified source as saying: "We know who djd it. We just have to prove it." The source would not identify the suspect or the evidence beingsought or say why an arrest has not beenmade, the newspaper said.

"I really couldn't make a comment either way about it," said Cmdr. Edward M. Cisowski of the Illinois Department of Law Enforcement in response to the report. "Our official stance is no comment." Spokesmen for the FBI and Chicago police, both of which have played major roles in the investigation, denied knowledge of such a suspect.
