News4Jax played the audio recording for Lonna Barton's estranged husband, Chris Barton, who was in court Wednesday for her first appearance. He confirmed the voice on the tape was Lonna Barton's, and he was visibly upset when he heard her talking about their missing son. But he said he still doesnt believe Lonna Barton had anything to do with Lonzie's disappearance.
Florida law requires consent from all parties for recording or disclosure of contents of any wire, oral, or electronic communication (unless in a setting where a person doesn't have a reasonable expectation of privacy). So this recording won't be admissible in court. That being said, it sure can't hurt that it adds pressure and could encourage someone to talk more...
