Judge finds N. Providence man not guilty in 2010 killing of his mother

NORTH PROVIDENCE, R.I. -- Due to his insanity, a former North Providence school teacher was found not guilty of murder when he beat his mother to death with a baseball bat in March of 2010, Superior Court Judge Susan E. McGuirl said Thursday.

McGuirl reached her decision after reviewing the findings of two psychiatrists who both concluded that Maciocio has bipolar disorder and was in a state of psychosis when he killed his 63-year-old mother, Mary Ann Maciocio.

For that reason, Maciocio was not criminally responsible for killing his mother, McGuirl said.
