TROY (AP) -- A 35-year-old upstate New York man has been sentenced to 25 years to life in prison for killing a mother of six while she worked at a group home for the developmentally disabled nearly two decades ago.

Local media outlets report Scott Chaplin was sentenced for the second-degree murder conviction Monday in Rensselaer County Court. He'd been found guilty in July of beating 47-year-old Rosemary Crosier to death with a tire iron as she was working the overnight shift at a group home in Troy in March 1994.

Prosecutors linked Chaplin to the slaying through DNA evidence found at the scene. Police said Crosier was killed during a robbery.

In January, 42-year-old George Mott III was acquitted of murder charges in the slaying.
