The video is not released publicly but the family and their attorney is still able to describe what they saw.
They say the video shows their son, Samuel Hayes Jr. offer his hands and allow himself to be handcuffed by jail staff before collapsing to the ground multiple times before being carried to and placed in the restraining chair.
The video shows the jail violated policy with the use of the restraining chair according to Attorney with the Khazaeli Wyrsch Lawfirm Jack Waldron.
"Somebody should have a thorough medical vetting before they get into the [restraining] chair."
However, says Waldron says that did not happen.
"We saw corrections officers take him directly into the chair despite the fact that he was limping despite the fact that he wasn't moving strong."
The family says that while Hayes was checked a few times early on, he went an hour and a half without being checked. Waldron says this is when Hayes can be seen suffering a medical episode.
"We saw him continue to convulse for fifteen or twenty minutes. At which point he stopped moving."
Hayes's mother said she saw her son take his last breath in that moment.
"I literally seen his chest raise up and then it went back down and then he just slumped over and closed his eyes."
Waldron says the lack of checking on Hayes is why he died.
"They would have been able to get [him] treatment but he was by himself."
They also claim Hayes was barely in the video initially.
"In the first moments of the video when he was put in the chair you could only see about his forehead," said Waldron, adding Hayes upper body only entered the frame when he scooted the chair back.
The family says they intend to sue. They are also holding a vigil for Hayes outside the City Justice Center Saturday evening at 6. KMOX reached out to a spokesperson for the City Justice Center for comment and has not heard back.
