POPLAR BLUFF, Mo. (AP) — A Missouri man who spent eight years behind bars for murder has been acquitted in a retrial.

Michael Amick, now 40, was initially convicted of second-degree murder and second-degree arson in the 2008 death of his wife’s grandmother in southeast Missouri. The Missouri Supreme Court ordered a retrial last year.

The St. Louis Post-Dispatch reports that a jury on Thursday found Amick not guilty.

The conviction was overturned when the Supreme Court ruled that the trial judge violated state law when he called back an alternate juror, who had already been discharged, to take over for another juror who developed health problems after five hours of deliberations.

Leona Maxine Vaughan was 67 when she was shot and burned in Oregon County, near the Arkansas border.
