LOS ANGELES (AP) — A Los Angeles man sentenced to 27 years to life in prison for a decades-old slaying will be freed after two sisters of a key witness said the account of what her sibling saw was a lie.

The Los Angeles Times reports a judge threw out the conviction of53-year-old Kash Delano Register on Thursday. Register was convicted of killing 78-year-old Jack
Sasson in April 1979, but has always maintained his innocence.

Register was convicted mainly on eyewitness testimony. Brenda Anderson identified Register as the gunman, even though he had an alibi that he was with his girlfriend at the time of the shooting.

Two of Anderson's sisters said their sibling lied about seeing Register running away from the crime scene. Brenda Anderson has repeatedly changed her account.
