Police in Michigan have promised to reveal dashcam video of the fatal shooting of a Black man on Friday, after calls for the release of the video became louder over the weekend.

According to Grand Rapids Police Chief Eric Winstrom, 26-year-old Patrick Lyoya was shot and died after being stopped for an unregistered licence plate on April 4.

Winstrom said that after a “lengthy battle,” Lyoya got out of his car, ran away short, and was fatally shot.

Lyoya’s family denies that claim, alleging they saw video of the incident in which he was shot in the back of the head while lying face down on the ground.

“Yep, I caught that one. I couldn’t get any rest. The youngster had collapsed on the ground. On Sunday, Israel Siku, the Lyoya family’s interpreter, told a community meeting in Grand Rapids that the police officer was on his knees when he drew his revolver and shot him in the head. Swahili is the mother tongue of the family.

When Lyoya and his family arrived in the United States in 2014, they were fleeing the war-torn Democratic Republic of Congo.

Dashcam video showed to Siku and Lyoya’s father revealed the shooting to have been “execution style.”

Siku stated in an interview on Monday that Lyoya’s mother is “in full shock” and that the family is “still mourning, puzzled, and heartbroken.”

In the wake of Lyoya’s death, she leaves two young children.

According to Winstrom, an officer who is white and has been with the department since 2015 was put on administrative duty while the MSP investigated. No one has been named as the cop involved in this incident.

To meet his deadline of “no later than noon on Friday, April 15,” Winstrom stated in a statement he will disclose the footage.

Kent County Prosecutor Chris Becker wants the footage held until the state police investigation is complete, and Winstrom’s commitment puts him at conflict with Becker.
