PHOENIX -- The Arizona Supreme Court on Friday unanimously upheld the convictions and sentences of a death-row inmate from Hawaii in the killing of his mother in Arizona.
John Vincent Fitzgerald was convicted of killing Margaret Larkin in her Sun City West home on April 15, 2005, the day he traveled to Arizona from Hawaii.
Larkin was a recently retired nursing professor at Glendale Community College.
A Maricopa County Superior Court jury rejected Fitzgerald's insanity defense and convicted him of first-degree murder and burglary.
A mistrial during the penalty phase of the case resulted in the impaneling of a second jury for sentencing.
The second jury sentenced Fitzgerald to death on the murder conviction.
A judge sentenced Fitzgerald to 10.5 years in prison on the burglary conviction.
