The woman, who is in protective custody, told Local 6 News that her ex-husband has a history of murder, has confessed to shooting a woman at close range and is a paranoid schizophrenic.

Local 6 News has learned that investigators are looking into the woman's claims and where her ex-husband was when Iwana Patton, Laquetta Gunther and Julie Green were killed.

She said detectives collected DNA evidence from her home and they are waiting on a positive match from DNA found at all of the crime scenes in Daytona.

The woman told Local 6 News that she feels guilty every time she thinks about the women who have already been murdered.

"I don't think he is ever going to stop until he is dead or he is incarcerated for the rest of his life," the woman said. "I won't feel safe until one of those two things happen."

Police said all of the victims got into cars with a stranger and were later found shot to death and dumped in secluded areas.

Anyone with information concerning this crime is urged to call Crimeline at (800) 423-TIPS.
