Investigating Innocence is a nonprofit wrongful conviction advocacy organization that provides criminal defense investigations for inmates in the United States. Investigating Innocence was founded in 2013 by private investigator Bill Clutter to assist nationwide Innocence Project groups in investigating innocence claims. "Once we have a case that meets our criteria, we'll put private investigators to work on it. A lot of these cases need investigators," said Kelly Thompson, executive director of Investigating Innocence. Prior to his work on Investigating Innocence, Clutter was one of the founders of the Illinois Innocence Project. Investigating Innocence also has a board composed of exonerees that reviews incoming cases.
