Robert Joseph Marder

A man was sentenced in federal court to a 78-month prison sentence for assaulting a woman with a piece of door trim that had a nail protruding from it while she was holding her three-month-old daughter, according to Acting U.S. Attorney Clint Johnson.


Following his term of imprisonment, Robert Joseph Marder, 32, will serve three years on supervised released.


“Robert Marder will spend more than six years in federal prison for terrorizing the victim and her child with his abusive conduct and for trying to prevent the victim from cooperating with authorities. Make no mistake, children also suffer the immediate and long term effects of violence in the home,” said Acting U.S. Attorney Clint Johnson. “After living under the control of an abuser, it can be difficult for domestic violence victims to cooperate with authorities. I want to assure victims that my team of federal prosecutors and victim specialists are here to seek justice on their behalf, to support them as their cases are being prosecuted, and to help them find needed resources so they and their children can move forward from abusive relationships.”


Marder pleaded guilty July 14, 2021, to assault with a dangerous weapon in Indian Country.


On May 29, 2020, Marder showed up at a former girlfriend’s home and became aggressive. The woman, accompanied by her three-month-old, attempted to leave the apartment. The defendant followed her to her car, so she ran back to the apartment and locked the doors. Marder kicked in the door causing the door trim to break. He then exited the apartment but came back through a window and continued the argument. While the victim was holding her child, Marder picked up a piece of trim with a nail sticking out of it and struck the victim multiple times on her forehead, shoulder and back of the head.


During the assault, the apartment’s security officers heard screaming. After arriving at the apartment, they witnessed Marder striking the victim with the trim. Security detained Marder and called police. The victim was transported to the hospital for treatment.


Marder is a citizen of the Cherokee Nation, and the crime occurred within the Muscogee Nation reservation.


The FBI and Tulsa Police Department investigated the case. Assistant U.S. Attorneys Justin G. Bish and Benjamin D. Hargrove prosecuted the case.
