Federal investigators now have an eyewitness to murder.

Kenneth McLaughlin says he watched Jacksonville police officer Karl Waldon kill bank customer Sami Safar.

It is the break they had been waiting for.

What happened next triggered stunning developments in the investigation into police corruption.

Federal investigators are stunned to have now learned their initial investigation into one police officer tipping off drug dealers has now exploded into other crimes involving three Jacksonville cops, ranging from home invasion to carjacking. And as their star witness is about to reveal — murder.

Federal investigators now have another suspect in their investigation into bank customer Sami Safar’s kidnapping and murder: another police officer, Karl Waldon.

Investigators think Waldon and Officer Aric Sinclair worked together to rob the convenience store owner.

But the murder was two years earlier and they had no physical evidence to link anyone to his death.

In the third episode of the series, a team of federal investigators had confirmed JSO officer Aric Sinclair had been using the power of his badge to steal money and drugs from suspected drug dealers for at least two years — and his greed was escalating.

In the second episode of Florida Justice: Betraying The Badge, a team of federal investigators have just uncovered a secret while listening to a wiretap conversation of a notorious drug dealer: A police officer with the Jacksonville Sheriff’s Office was leaking information about drug investigations.

A wiretapped conversation between a pair of drug dealers includes five words that turn a narcotics case into a police corruption investigation that reveals a stunning web of deceit spun by officers within the Jacksonville Sheriff’s Office.
