Floyd Bledsoe walked out of prison last December after 16 years in jail. Bledsoe was freed after government lawyers in Kansas decided that a court’s 2000 ruling against him was a mistake. The court found him guilty of killing his sister-in-law. The U.S. National Registry of Exonerations says Bledsoe was one of 149 prisoners cleared of criminal charges last year. That is the largest number of exonerations ever, it reported this week. The registry is part of the University of Michigan Law School. “There is a growing awareness that false convictions are a substantial, widespread and tragic problem,” the report said. More than two-thirds of those cleared last year had been jailed for killings or drug cases, the registry said. Five people were sentenced to death. Floyd Bledsoe was 23 years old when he was sentenced to life in prison in 2000.
