OKLAHOMA CITY - Testimony wrapping up today inside a federal courtroom as a judge prepares to make a decision in stopping Oklahoma executions.
Today, the court mainly heard about what went wrong in the execution chamber.
One paramedic told investigators, "Black people have smaller veins than white people."
The plaintiff's witness, an expert emergency room doctor says it's untrue.
"In a situation like this where medical personnel are actively trying to put somebody to death, you need accuracy, you need precision and in this particular case it doesn't seem like it's there," Ed Blau, a legal expert told us.
In an interview with investigators, the paramedic also said inmates, "are very muscular and they have a very strong heart and it takes a while for that heart to realize that it doesn't have to beat anymore."
The plaintiffs doctor says that's not how medicine works, saying there's a lack of medical experience.
"There's not a long list of people wanting to go in and actually execute somebody. This is probably a situation where the physician involved and the medical personnel were all they could find," Blau said.
The state tried to explain there was sufficient training to find the veins.
The defense focused more on Lockett's autopsy, repeating findings that he was "judicially executed by lethal injection."
They say no one except Lockett can prove he was in severe pain at the time of the execution.
"Anybody that's willing to put a hood over their head and get paid $300 to kill somebody that's generally not somebody at the top of their profession and in this case I believe it shows that very clearly," Blau said.
The judge says he will make a decision on Oklahoma executions by Monday afternoon.
