But body camera footage released by Louisiana authorities after campaigning by Greene's family shows him beaten while shackled.
The initial state police report on Greene's death does not mention state troopers using force or an arrest. You can hear him talking to a fellow officer at. Louisiana police initially accused him of his death in a vehicle accident and did not mention the use of force by police officers.
But the body-camera (body-cam) footage acquired by Associated Press and released by authorities late on May 22 shows a horrific scuffle.
The footage and the autopsy report add to the growing wealth of details about Greene's death, which has always been surrounded by allegations of a cover-up and is now the subject of a federal civil rights investigation.

"The trooper's wrong and what he did is excessive", said Charles Key, a use-of-force expert and former Baltimore police lieutenant.
Police are highly discouraged from leaving handcuffed suspects in a prone position, particularly when they aren't resisting, because it can greatly hinder their breathing - a point made repeatedly at the trial this spring of the former Minneapolis officer convicted of murder in the death of George Floyd.
"The officers involved in these investigations will be given due process", said Davis.
On Friday, Davis offered his "sincere condolences" to Greene's family and said the department has and will continue to make "significant change".
But a written police report later said Greene survived the crash and struggled with troopers trying to arrest him.
An autopsy showed that Green had alcohol and cocaine in his system, suffered multiple injuries from the crash, as well as injuries from a physical struggle. It said an independent autopsy had found severe head injuries that were inconsistent with a auto crash.
In the latest video, Green has his legs tied, his hands folded behind his back, prone to falling to the ground, and two soldiers floating above him before suddenly yelling.More news: Cuomo says NY reviewing CDC guidance on masks
"I'm your brother! I'm scared!" One of the officers tells him, "Yeah, yeah, that s-- hurts, doesn't it?"
Greene the screams out: "OK!"
Green's mother Mona Hardin said she had initially told her son had been killed in a vehicle crash.
A SUPERVISOR praised state troopers who tasered a black man and left him facedown for nine minutes before he died, new video has revealed.
The new video, recorded on Lt. John Clary's body camera, remained under wraps for months even within State Police but was recently turned over to the FBI as part of its investigation, according to three law enforcement officials.
The newly-released bodycam footage shows a high-speed chase and Louisiana state troopers punching motorist Ronald Greene when he was already in handcuffs. As I've said before, I found the full video of Mr. Greene's arrest, which I reviewed previous year, to be disturbing and hard to watch.
