A Texas man who spent 19 years in prison for the killing of a friend has been freed after a witness said he lied and a bloody palm print at the crime scene was linked to another person.

Forty-two-year-old John Earl Nolley walked out of Fort Worth courtroom on a personal recognizance bond Tuesday while his innocence claims are considered.

Nolley's conviction was based largely on testimony from a jailhouse snitch who later said he was lying. New test results show the palm print does not belong to Nolley or the victim, Sharon McLane.

Nolley was sentenced to life in prison in 1998 after being convicted of murder in McClane's 1996 slaying in Bedford.
