Joseph Sledge spent more than half of his life in prison. But on Friday, he walked out a free man, cleared of two murders he never committed.
Sledge, now 70-years-old, was convicted in 1978 of stabbing a mother and her adult daughter, the Associated Press reported. For the killings, a judge sentenced him to life in prison.
The 1976 stabbings happened in Elizabethtown, North Carolina, at the same time that Sledge had escaped from a prison work program. He had been serving a four-year sentence for larceny, according to the AP.
The break in Sledge's case came when court clerks found a misplaced envelope of hair that was believed to belong to the killer.
Court clerks discovered the envelope when they were cleaning out an evidence shelf in 2012. The shelf was apparently high up in the room.
"I understand those shelves were very high, but there was a ladder in that room," Sledge's attorney Christine Mumma told the AP.
The hair underwent a DNA test, and it turned out it wasn't Sledge's.
Other evidence used to convict Sledge also recently fell apart: In 2013 a key witness recanted his testimony, saying he lied because he was promised leniency in his own case. The witness has described Sledge as a racist who believed white women were devils, according to the Charlotte Observer, but later said investigators coaxed him into making the comments.
Court documents also show that another witness' testimony was inconsistent, the AP reported.
In fact, none of the evidence from the murder scene came from Sledge.
In December, a forensic expert testified that the fingerprints — along with hair and DNA — gathered at the scene also didn't match Sledge, ABC 11 reported.
