Carl Cavalier, a 33-year-old state trooper with the Louisiana State Police Department (LSPD) since 2014, said he has been fired for calling out colleagues and leaking internal records regarding the 2019 police murder and cover-up of a Black man.

Ronald Greene, a Black motorist, was beaten by the police, tased, bound and forced to lie face-down on the ground. Greene, 49, later died while in police custody.

Police told Greene’s family that he had died of injuries sustained in a car crash at the end of a chase that took place just outside of the city of Monroe. Greene’s vehicle, however, showed little damage to support that claim.

Body camera and dash-cam videos released to the public two years later show Greene was tased, kicked, and punched by LSPD officers before he died in their custody, CNN reported.

Two troopers involved in the incident were reprimanded that night, and a third was reportedly going to be terminated for violations regarding body-worn camera and car camera systems, use of force, performance, lawful orders, and for conduct unbecoming an officer. But there was no punishment for their alleged part in Greene’s death.

Frustrated that there had been no media coverage or questions asked, Cavalier decided two years later to give a tell-all interview with Baton Rouge ABC-TV affiliate WBRZ. He detailed what he believed to be a cover-up about Greene’s death designed to help the officers involved avoid charges.

“I love what I do,” Cavalier said at the time in the tell-all, “but we still have murderers, in my eyes, on the job. Guys who received a slap on the wrist for their roles in the Ronald Greene incident are unpunished… patrolling the streets, and left on the job.”

Cavalier was suspended in March and placed on a five-week paid leave for leaking internal state police files during his appearance in multiple interviews related to the investigation, Yahoo reported.

Cavalier said he’s been on paid leave since August. He shared a letter with NBC News dated Oct. 8, signed by Louisiana State Police Superintendent Lamar A. Davis, notifying him of his potential termination within 45 days.

He has since received notice that he will be terminated. A spokesperson for the LSPD told Fox News that Cavalier was let go for violating department policy.

“Trooper Cavalier received the decision of the appointing authority to move forward with termination based on an administrative investigation that revealed he violated several departmental policies,” the spokesperson explained.

The firing follows a September lawsuit Cavalier filed against the department accusing his superiors of harassment and discrimination, Yahoo reported.

According to the lawsuit, Cavalier claims his problems began soon after he issued a ticket to a Houma, Louisiana, police officer in 2018, WBRZ reported. Documents also alleged that state police personnel began harassing Cavalier’s relatives over minor traffic violations.
