Michigan’s attorney general is investigating the death of a black man who was struck by an unmarked police car

The family of a Black man killed after being struck by an unmarked police car in Michigan spoke out Saturday after investigators released body camera footage of the incident.

Michigan State Police said it has turned over to the attorney general’s office its investigative report and all evidence in the April 17 death of Samuel Sterling, who was being pursued by officers in Kentwood on outstanding warrants.

Sterling, 25, allegedly fled when officers approached him at a gas station and was struck by an unmarked Michigan State Police car after officers ran toward him in a nearby Burger King parking lot, police allege. He died in hospital later that day.

Body camera footage released Friday showed officers rushing to Sterling on the ground after he was hit, groaning in pain and claiming he had no weapon. The unmarked police vehicle is parked on a curb next to the restaurant in front of Sterling.

Attorney Ven Johnson, an attorney representing Sterling’s family, said in a statement to ABC News that they were “stunned and horrified to see the MSP trooper intentionally drive over a curb – onto a sidewalk – and violently drive Samuel.” took his life by hitting him with an unmarked police car.”

“No one should be able to appoint themselves judge, jury and executioner, yet deaths from police brutality and excessive force continue to occur too often,” Johnson added.

Officers can be seen handcuffing Sterling and telling firefighters who were on scene to keep the handcuffs on.

The footage released Friday came from three agencies that were part of the fugitive group — Michigan State Police, Grand Rapids Police Department and Wyoming Police Department — and included footage from four sources, three body camera footage from officers and a dashcam from a police vehicle, said the Michigan State Police.

“I assure the Sterling and Cage families and the communities we serve that we will continue to be transparent in this investigation and will cooperate fully with the Michigan Attorney General’s Office as they begin their review,” said MSP Director Col. James F Grady II, who met with the family on Friday, said in a statement.

The state trooper driving the vehicle that hit Sterling was not wearing a body camera and his vehicle did not have a dashboard camera “due to his assignment on a federal task force,” Michigan State Police said in a statement.

State police opened an investigation into the incident and suspended the trooper – whose identity was not released pending the investigation – without pay.

Marc E. Curtis, the attorney representing the officer, told ABC News in a statement that his client is cooperating with the investigation.

“We want to let the family and community know that we know you are grieving over the death of Mr. Sterling. The trooper involved is heartbroken over the loss of Mr. Sterling’s life and wants the family to know that he had no intention of intentionally “causing harm to Mr. Sterling,” Curtis said in a statement.

Michigan Attorney General Dana Nessel will review the police report and evidence and decide whether charges are warranted.

“My Public Integrity Unit has investigated dozens of incidents involving police and is committed to providing a thorough and fair review and resolution for each and every incident,” Nessel said in a statement last month.

Gov. Gretchen Whitmer said in a statement Friday that Sterling’s death was “unacceptable” and called for the officer to be fired if charges are filed.

“I have every confidence that her office will work quickly to make a fair and equitable decision about whether criminal charges are appropriate,” the governor said of Nessel.
