An upstate New York man has been charged in the cold case death of his wife 16 years ago.
Casey Callahan, 50, is accused of running over Elizabeth Callahan with a tractor trailer in 2000, according to the Oneonta Daily Star.
He pleaded not guilty to a murder charge Monday in Otsego County Court and is expected to be assigned a public defender. Callahan was brought to court from Attica Correctional Facility, where he's serving time for a 2013 sex crime conviction.
Elizabeth Callahan was 34 when she died in what was originally investigated as an accident in a Pennsylvania parking lot. But some of her relatives convinced authorities to look into the possibility she'd been killed. No charges were brought until the case was reopened in March.
