In October 2017, a jury convicted Robert Burton of murder in the July 2015 death of Stephanie Ginn Gebo.
After Gebo's body was discovered at her Parkman home, Burton evaded capture for 68 days.
A Bangor judge sentenced Burton to 55 years in prison on the murder conviction. However, Burton's attorney claimed among other things that the trial judge mistakenly let jurors know about two of Burton's previous burglary convictions.
The decision released Tuesday stated that members of the Maine Supreme Court denied Burton's request to overturn the murder conviction.
