DOVER-FOXCROFT, Maine (AP) – A 53-year-old Dover-Foxcroft man has pleaded not guilty to murder in the death of his older sister. Michael Toby entered his plea Monday in Piscataquis County Superior Court. He is charged with killing 70-year-old Rosalie Shedd in her apartment in Dover-Foxcroft in October. Police say Toby told them he struck his sister repeatedly on the head, strangled her with a vacuum cleaner cord and put a plastic bag over her head after they got into a fight. Toby’s defense attorney, Christopher Smith, says he’s waiting to get more evidence from prosecutors before deciding how to proceed with the case. Toby is being held without bail in the Piscataquis County Jail.
