Worthy: Jessica Cooper Was Wrong To Hold Child-Killer News Conference

Wayne County Prosecutor Kym Worthy told the Detroit News Oakland County Prosecutor Jessica Cooper was off base for naming a person of interest in the Oakland County child killer case and releasing DNA test results.

Worthy told the paper those actions "severely compromised our investigation."

Cooper's press conference Tuesday revealed what was described as a breakthrough in the murders of four Oakland County children in 1976 and 1977. Cooper named convicted pedophile Archibald Edward Sloan as a person of interest in the case and said that a hair found in Sloan's red 1966 Pontiac Bonneville has the same mitochondrial DNA profile found on victims Mark Stebbins and Timothy King, the first and final victims.

 Worthy, who is also investigating the case because one victim's body was found in Wayne County, said the information should not have been made public while investigators continued their work.

 Cooper said there are several new leads in the case, thanks to the news conference.
