Gacy's blood may solve old murders

CHICAGO (AP) -- Illinois authorities are hoping to solve the coldest of cold cases with help from John Wayne Gacy's blood. And they're taking an extremely unusual approach to gain access: exploiting the fact that death of the notorious serial killer himself was, legally speaking, a homicide.

Officials in Cook County, which encompasses Chicago, say it's a game of scientific catch-up. The Sheriff's Department is creating DNA profiles of Gacy and other killers executed long before DNA became a standard component of crime scene analysis.

The only way state officials would allow the profiles of Gacy and the others to be included in the DNA database was to essentially have the killers themselves considered as homicide victims. Because they were executed, the death certificates list homicide as the cause of death.
