The Utica man accused of killing his grandmother and their landlord in early 2019 has pleaded guilty to both homicides in County Court.
Following years of psychiatric examinations and treatment, Naythen A. Aubain, 30, pleaded guilty before Judge Robert L. Bauer Friday morning to two counts of second-degree manslaughter, reduced from second-degree murder, according to court officials. Aubain accepted a sentence of 15 to 30 years in state prison.
Aubain is scheduled to return for sentencing on March 25.
Police said Aubain killed his 90-year-old grandmother, Katerine Aubain, and their 87-year-old landlord, Jane Wentka, sometime in early January 2019 at their home on Tilden Avenue in Utica.
Police said Aubain mutilated the bodies and buried his grandmother in a shallow grave in Clayville, while Wentka’s body was found in her apartment. Authorities said Aubain also killed Wentka’s pet dog.
He was taken into custody following a motor vehicle accident on Jan. 6, 2019. It was initially determined that Aubain was not mentally fit to assist in his defense, and he underwent months of psychiatric treatment — until the fall of 2019, when he returned to court.
Since then, Aubain had been undergoing mental health evaluations from both the prosecution and the defense, with his case adjourned multiple times over the past few months — until today’s guilty plea.
