For the first time publicly, the ex-lover of Dalia Dippolito testified about coming forward to police.
After initially coming forward, he claims he was pressured by Boynton Beach Police detectives to cooperate or face prosecution.
He told a judge on Tuesday that he was not aware that the situation was being filmed for an episode of Cops until he saw a clip on YouTube.
Dippolito was convicted of hiring a hitman to kill her husband.
She is now getting a second trial, but her attorneys are hoping to get the charges against her dropped before the trial even starts.
"Whether you like her, or not, she is afforded the same constitutional rights as all of us and the testimony today of the undercover informant in this case categorically validates that the Boynton Beach Police Department broke all the rules and violated Ms. Dippolito's rights," Defense attorney Brian Claypool said.
The pretrial hearings will continue in February.
Dippolito is expected to take the stand then.
Boynton Beach Police say they stand by their detectives work and look forward to another successful prosecution.
