OKLAHOMA CITY -- The family of Robin Howard is facing off with the Oklahoma City police department again.
In their second protest across the street from the department, they say they still have no answers.
"We can't move on until we know the truth. We can't even grieve. We can't do nothing. We got no peace," said Howard's sister, Deidra Hill.
Robin Howard, 54, was arrested two months ago after leading police on a brief chase and crashing his car.
Officers took him to the hospital where he died four days later.
The medical examiner ruled the death a homicide, acute pneumonia brought on by blunt force trauma to the chest.
"If you looked at his body, you could tell how badly they whooped him," said family friend, Donald Williams.
"We want to know what happened that day when they pulled him over and all these bruises you know all this different stuff happened to him. We want to know that," said Kimberly Turner, another of Howard's sisters.
The Howard family attorney, David Slane, has written a letter to the ACLU asking for their help in the case in getting documents from the police department.
Slane also says the medical examiner is not releasing two key pieces of the autopsy: the diagram of the body showing all injuries and the summary.
"I've received autopsies for almost twenty years in my work and I've never seen them historically withhold this," said Slane.
"We want answers. We want police reports. We want documentation. We want everything we can possibly get to get answer of why," said Howard's sister, Brandy Howard.
The family says they won't stop until they get those answers and justice for Robin.
Captain Dexter Nelson with the Oklahoma City Police Department says whenever the family wants to talk, they can call detectives and sit down and talk with them.
But, he does say they may not be able to answer all their questions.
The police investigation has been turned over to the district attorney.
He will ultimately decide if the officers involved used excessive force or failed to follow proper procedures.
