The family of a man who died after being restrained in an Ohio jail says the deputies who piled on him stood by for several minutes without trying to save his life after he became unresponsive.

Attorneys for the family said the deputies and jail medical staff members who looked on as Christian Black sat slumped in a restraint chair should be criminally charged in his death.

“There was no sense of urgency,” said his father, Kenya Black. “You could clearly see he was unconscious.”

Black, 25, of Zanesville, died on March 26, two days after he was taken from the Montgomery County jail to a hospital in Dayton. He was in the jail after police said he crashed a stolen car.

The county coroner’s office said last week that Black likely died from positional asphyxia, which happens when the chest can’t expand, starving the body of oxygen. His death, which is still under investigation, was ruled a homicide by the coroner.
