Former Mahoning County judge Maureen Cronin turned in a written plea of not guilty today, to charges of driving under the influence. The judge hearing the case ruled that the dash cam video of her arrest should not be released. Cronin was pulled over late Wednesday night for D-U-I, and police say she refused to take the sobriety test. Cronin plead "no contest" to D-U-I two years ago. She lost her license for six months.
