Late on Wednesday, Daniel Holtzclaw, the former Oklahoma City police officer convicted in December of raping and sexually assaulting eight women while on duty, filed a request for a new trial, the Associated Press reports. His sentencing hearing is scheduled for Thursday.

The defense team is arguing that a Facebook post published subsequent to the jury’s verdict is new evidence in the case, KOCO.com reports. Court documents claim that the former police officer was denied a fair trial because “the government made deliberate discovery violations and misrepresentations, undermining confidence in the verdict.”

The request, filed by attorney Scott Adams, asks for either a new trial or an evidentiary hearing. Holtzclaw faces up to 263 years served consecutively.
