Kronk's ex-wives talk to Anthony defense team

For the first time, we're hearing from former meter reader Roy Kronk's ex-wives. Their testimony is part of a defense tactic. Casey Anthony's lawyers claim that there is as much circumstantial evidence against the man who found Caylee Anthony's remains as there is against Caylee's mom, Casey.

In video admitted as part of some motions filed this week, we hear directly from Kronk's ex's. "He duct taped my hands one time," said Jill Kerley, Kronk's second ex-wife. "How often did he duct tape you?" asked a Private Investigator for Casey Anthony's defense team. "There were two occasions," said Kerley. "You mentioned he had a certain saying about duct tape?" asked the PI. "Yeah .. it's 100 mile per hour duct tape ... nothing can get through it," said Kerley.

In the motions, the defense states this "evidence indicating that Mr. Kronk has a history of abusing, restraining and holding women against their will," and that he has used duct tape, "for the purpose of restraining women."

Kerley says she had a strong gut feeling when she learned that Kronk found Caylee's remains. "When you heard Roy Kronk found the remains of Caylee Anthony, what had gone through your mind?" asked the PI. "That he had done it," said Kerley. "What do you mean?" asked the PI. "That he was the one who killed Caylee," Kerley responded.

Another ex-wife, Crystal Sparks, says Kronk's father once asked her to bail his son out of jail after getting arrested for kidnapping a girlfriend. In an interview the Private Investigator, she quotes his father as saying, "Crystal, there were handcuffs, duct tape and he used a plastic gun he bought at a drugstore."
