“The DOJ must truthfully determine whether a pattern and/or practice of discrimination played a role in the case of DJ Henry — and if it did — deliver the justice that restores this young man’s name and reputation, while giving hope to other young black men who are just like him and desperate for change,” they wrote.

Others who signed the letter are Pharrell Williams, Taraji P. Henson, Odell Beckham Jr., Michael K. Williams, Kerry Washington, Mary J. Blige and Gabrielle Union.

An email seeking comment was sent Friday to DOJ spokespeople.

Federal prosecutors in the Southern District of New York announced in 2015 that they would not bring civil rights charges, saying a thorough review of evidence did not show that Pleasantville officer Aaron Hess acted with deliberate and specific intent to break the law. The officer was previously cleared by a grand jury.

Hess shot Henry as Henry drove through a parking lot, away from a disturbance that spilled out of a bar in October 2010 in Mount Pleasant, a New York City suburb.

Hess has said Henry was trying to run him down and that he fired through the windshield to stop the driver.

The Henrys have said Hess jumped front of the car, got onto the hood and shot their son for no good reason. Another officer, Ronald Beckley, shot at Hess, later saying he did so because he believed Hess was “the aggressor.”

Prosecutors said Henry’s car struck the officer and injured him before Hess fired his weapon as he made “a split decision under conditions of extreme danger, conditions under which the law generally allows latitude to a police officer’s judgment.”

The Henrys reached a $6 million settlement with the town and the officer.

The celebrities said the facts of the case “reek of local conflict of interest, racial bias and even false testimony.”

“Justice, it appears, has been denied,” they wrote.

Henry’s father said new information that has come out since the criminal case was closed warrants a reexamination of his son’s death.

“As human beings we should all want a standard of justice that is fair and right,” Danroy Henry Sr. told The Boston Globe. “And it just wasn’t in the case of our son’s murder. . . . We should just get an honest, transparent review of the facts. That’s all we’re asking.”

Jay-Z has also called for justice in the case of Ahmaud Arbery, a Black man who was shot and killed as he ran through a Georgia neighborhood. The social justice arm of Jay-Z’s Roc Nation entertainment company in May called on the state’s attorney general to appoint a special prosecutor to help achieve a fair trial.
