Answer:
David Milgaard
"...Twenty years for nothing, well that's nothing new
Besides, no one's interested in something you didn't do."
This lyric outlines the sentence given to David Milgaard in 1970 even though it was later determined that he never committed a crime in the first place. In 1969, Milgaard and his friends Ron Wilson and Nichol John were taking a road trip across Western Canada. At the time, Milgaard was 16 years of age. Police had discovered the body of a nurse named Gail Miller. At the time of their arrest, Milgaard and his friends were going to pick up another friend named Albert Cadrain who was renting a basement apartment to a man named Larry Fisher. While Wilson, John, and Cadrain knew of Milgaard's innocence, they testified against him anyways. In 1970, Milgaard was sentenced to life imprisonment.
After years of appealing his sentence, the Saskatchewan government entered a stay of proceedings (halting of a new trial) as it was determined through DNA and other evidence that Milgaard had never committed the murder in the first place. Milgaard's sentence was overturned and he was released from prison. In 1980, the ex-wife of the tenant Larry Fisher had made a statement that she believed her ex-husband had actually committed the crime but authorities did not follow up on her statement. Through new technologies, it was determined that Fisher was the real killer and in 2000, he was sentenced to life in prison. In 2015, Fisher would die in prison.
