WEST BATH, Maine (AP) — A Maine teenager has pleaded not guilty to killing his grandmother last year.

Dominic Sylvester was 16 when 55-year-old Beulah "Marie" Sylvester was found unconscious inside their Bowdoinham home. He pleaded not guilty Tuesday in West Bath District Court.

Sylvester was initially charged as a juvenile. But a judge has ruled Sylvester, now 18, will be tried as an adult on a charge of depraved indifference murder, which carries a sentence of 25 years to life.

Court records indicate he called 911 in February 2018 and told detectives at the hospital that he had hit his grandmother on the head with a stick.

He is being held at Two Bridges Regional Jail without bail. No trial date was set Tuesday.

Sylvester's attorneys didn't immediately respond to request for comment Wednesday.
