CHICAGO (CBS) — For the first time, a sample of John Wayne Gacy’s blood has been entered into a nationwide system to see whether Gacy committed more than the 33 murders that authorities know about.

Cook County Sheriff Tom Dart tells Newsradio that vials of Gacy’s blood were discovered in storage.

Dart says that several weeks ago, for the first time, Gacy’s blood was entered into a federal database.

“And there are some live cases that people are now working with that they think there might be some potential there,” Dart said.

“One [case] is out of Michigan, and there’s another one out of another state.

“It’s more tenuous at this point. But the one in Michigan is eerie because not only does it fit the profile a million different ways, but we actually have travel records that we found in our search that put him in that general area.”

Dart says blood was taken from Gacy when he was executed in 1994, but he says it was never entered into a database.
