The Midwest Innocence Project spent seven years investigating his case.
Director Tricia Bushnell told 41 Action News Thursday their cases involving Morehead are getting closely examined.
"We had individuals whose cases were touched by these same actors already on that waitlist. Those are the cases that we are giving a hard look to say, 'Is this something that happened again?'" Bushnell said.
A spokesperson for the U.S. Attorney's Office in Kansas has been told not to comment on the accusations surrounding Morehead.
"I think the number one thing about the justice system is it's a human system. There are human actors in every aspect of it. So we have to be able to say humans make mistakes and we can fix them, but when we see repeated mistakes over and over and they go uncorrected that's on us. It's our job to fix them to stand up and say it's not OK," Bushnell said.
Both the U.S. District Court and the U.S. Attorney's Office have the power to sanction Morehead but as of Thursday haven't taken any action.
