The Rev. Al Sharpton and family members of an Ohio man who died in police custody told mourners at his funeral on Wednesday that they and the community must fight to see that he gets justice.

Sharpton gave the eulogy for Frank Tyson, a 53-year-old East Canton resident, during the service at the Hear The Word Ministries church in Canton. Tyson died April 18 after he was handcuffed and left facedown on the floor of a social club while telling officers he couldn’t breathe.

“You can’t give us Frank back, but you can do justice for this family,” Sharpton said. “This is an assault on all us ... stand up for the Franks of this word, because if they can get away with what they did to Frank, they’ll do it to you.”

Tyson’s longtime partner, Sabrina Jones, noted that Tyson had been in prison for many years and was released less than two weeks before he died. She and members of his family had worked over the years on efforts to exonerate Tyson, who had long maintained his innocence.
