UTICA, N.Y. -- The suspect in a double homicide on Tilden Avenue in Utica did not appear at his scheduled hearing Wednesday morning, but new details were released in the case. 

Naythen Aubain, 29, is accused of killing his 90-year-old grandmother, Katherine Aubain, and their 87-year-old landlord, Jane Wentka, on Sunday night. 

According to the felony complaint, Aubain admitted to stabbing both victims in the neck -- dismembering them, and also detailed where he placed both of the bodies. 

The judge at his arraignment Tuesday night ordered a psychiatric evaluation for Aubain. He was unable to appear in court because of  his combative behavior, and 'unhygienic acts".

"His refusal to use his bathroom facilities in his cell have caused him to just be in a condition that you just wouldn't want him being out in a courtroom setting at the moment," said Maciol.

At his arraignment Tuesday night, Aubain, who was wearing a spit shield over his head, was vocal about the deaths of the two women. He said he "chopped them up"  in the "name of Jesus."

Utica police do say that the investigation is ongoing and additional charges could be filed. 

Aubain has been charged with two counts of first-degree murder. If convicted, he faces a sentence of life without parole in prison.

Aubain is being held in Oneida County Correctional Facility, until his next court appearance on February 11, at which time the results of the psychiatric evaluation, which will determine his fitness to stand trial, will be placed on the record.
