Tulsa Man Sentenced for Strangling Girlfriend

TULSA, Okla. – A Tulsa man was sentenced for strangling his girlfriend, announced U.S. Attorney Clint Johnson.

U.S. District Judge William P. Johnson sentenced Robert Alan Wickham, 39, of Tulsa, for Assault of an Intimate/Dating Partner by Strangling and Attempting to Strangle in Indian Country. Wickman was ordered to serve 46 months imprisonment, followed by three years of supervised release. 

According to court documents, Wickman physically abused his girlfriend for years, as evidenced by a lengthy criminal history for domestic abuse. In June 2025, his girlfriend was subpoenaed to testify in a court proceeding about the abuse. Wickman’s girlfriend told him that she had been subpoenaed. A few days later, Muscogee Creek Nation Lighthorse Police officers were dispatched to their home because Wickman struck and strangled his girlfriend again. This also violated a no-contact order that had been issued in a pending domestic violence case against Wickman in tribal court. 

Court documents show that Wickman’s criminal history spans nearly 20 years and includes four prior domestic violence convictions.

Wickman is a citizen of the Navajo Tribe and will remain in custody pending transfer to the U.S. Bureau of Prisons.

The FBI and Muscogee Creek Nation Lighthorse Police Department investigated the case. Assistant U.S. Attorney Stacey Todd prosecuted the case.
