A Fall River woman was sentenced to 8 to 10 years in State prison on Wednesday, after a Superior Court jury found her guilty of deliberately burning a foster child she was caring for. 

Police say the incident happened in 2009 at Kelly O'Brien's Walnut Street  home in Fall River. 

Prosecutors say O'Brien burned a young boy's arm with a hair straightening iron.  The boy suffered second and third degree burns and has since undergone skin grafting surgery. 

Judge Thomas McGuire imposed the 8-10 year prison term, plus ten years supervised probation.  District Attorney Sam Sutter says the case was very disturbing, and he's thankful for the jury's verdict
