ROCKLAND — The Maine supreme court has upheld the conviction and 45-year sentence for a Rockland man convicted of strangling his girlfriend to death in November 2010.
Prosecutors said Arnold Diana killed his 47-year-old girlfriend, Katrina Windred, in her apartment while her 11-year-old son was waiting outside in her car reading comic books.
Diana’s lawyers argued that the conviction should be overturned because, among other things, a victim of domestic violence was allowed to serve on the jury. The supreme court rejected his appeal on Thursday.
Prosecutors had said there was overwhelming evidence that he killed her after finding out that she had met another man.
