Jury Finds Man Guilty of Assaulting a Dating Partner

A federal jury convicted a man Friday who assaulted his dating partner in November 2020, announced U.S. Attorney Clint Johnson.

Alexander Michael Koloff, 29, of Tulsa, was found guilty of assault by striking, beating, and wounding.

During the domestic violence incident, Koloff, who had been drinking, took the victim’s phone so he could search through it. The woman asked him to return it when he was done, but he refused and eventually fled into a bathroom. As he tried to close the bathroom door, Koloff slammed the victim’s foot in the door injuring her. Next, Koloff slapped the victim, put his arms around her body and neck, and took her to the ground. Koloff then put his foot on her chest so the victim couldn’t move, took victim’s phone and fled the apartment,. The victim sought help from a neighbor and called 911. Koloff returned a short time later and locked himself in the apartment.

Officers responded to the incident and noted bruising and red marks on the victim that appeared consistent with the abuse described by the victim. An officer also conducted an on-scene lethality assessment with the victim, who identified to officers that she was in fear, was threatened, and had previously experienced violence from Koloff.

When performed, the on-scene lethality assessment can help police officers identify victims at high risk of homicide by their partners, ensure victims have a safe place to stay following a domestic violence incident, and place them in immediate contact with a domestic violence advocate.

The victim was later examined by a medical professional and found to have suffered multiple injuries including bruises and abrasions on her arms, back, chest, head and leg.

The Tulsa Police Department and FBI conducted the investigation. Assistant U.S. Attorneys Niko Boulieris and Kristin Harrington are prosecuting the case.
