Mark Verron Callshim, Jr., Robbery and Gun Violation, Oklahoma 2021

Published September 4, 2025

A federal jury in Oklahoma has convicted Mark Verron Callshim, Jr., 38, for Robbery in Indian Country and Carrying, Using, and Brandishing a Firearm During and in Relation to a Crime of Violence.

The crime occurred on November 2021, when two men arrived at a convenience store in a blue Subaru Forester. One man, later identified as Callshim, was seen wearing a black hoodie with the word 'savage' on the front, a black Cleveland Indians hat, with visible neck and hand tattoos. Callshim and the other suspect entered the store and pointed guns at the cashier, who was seen pulling money out of the register and visibly afraid of being shot.

Surveillance footage showed the cashier calling 911 as Callshim got back into the driver's side of the blue Subaru Forester and drove off while the other man fired one shot at the building. Tulsa Police officers responded to the 911 call and set up a perimeter to canvas the area.

A detective testified about responding to the scene where he looked for evidence and watched the surveillance footage. The footage allowed the detective to share the description of the two men seen in the footage and a description of the blue Subaru Forester. Shortly after the robbery, a citizen reported seeing a man in dark clothing abandoning the blue Subaru Forester nearby.

The detective contacted the victim of the stolen vehicle and explained that officers believed the vehicle was used in a robbery. The owner gave consent for the vehicle to be searched. During a search of the vehicle, officers found a partially smoked cigarette, among other things. The items were collected as evidence and submitted for DNA analysis.

Two DNA experts testified that the DNA collected from the cigarette matched Callshim's DNA. Court records show that Callshim has a lengthy criminal history, including assault with a dangerous weapon, possessing controlled substances, eluding an officer, and first-degree robbery. He is a citizen of the Ponca Tribe of Indians of Oklahoma and will remain in custody, awaiting sentencing that will be scheduled at a later date.

The second suspect involved in the robbery is still unknown. If you have any information about the second suspect, you can submit a tip to the FBI at tips.fbi.gov/home or by calling 405-290-7770. You can also submit an anonymous tip to Tulsa Crime Stoppers here or by calling 918-596-2677.

The FBI and Tulsa Police Department investigated the case. Assistant U.S. Attorneys Mike Flesher and John Brasher prosecuted the case. This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone.
