ALFRED, Maine (AP) — A 51-year-old woman police have charged with driving onto a baseball field and striking and killing a man is being held on $500,000 bail.

Carol Sharrow of Sanford, Maine, made her first court appearance in the manslaughter case on Monday. She's charged with killing 68-year-old Douglas Parkhurst and faces up to 30 years in jail. Click here for the video.

Sharrow did not speak during the brief court appearance in Alfred. The court also ordered a mental health evaluation. Sharrow will be eligible for the bail only if she gets a contract with Maine Pretrial Services, an organization that helps supervises individuals who are out on bail.

Sharrow's attorney declined to comment on a possible motive or whether Sharrow knew anyone at the field.
