Member of the Pagan’s Motorcycle Club Pleads Guilty for Assault Against a Rival Motorcycle Club Member

KANSAS CITY, Mo. - A member of the Pagan's Motorcycle Club pleaded guilty today before U.S. District Judge Greg Kays for his involvement in an assault against a member of a rival motorcycle club.

Mark A. Crump, also known as "Navajo," 55, of Lee's Summit, Mo., pleaded guilty today to one count of assault resulting in serious bodily injury in aid of racketeering.

On July 20, 2023, Crump, Jarrid A. Hammer, and another member of the Pagan's assaulted a lone rival motorcycle gang member at a bar & grill in North Kansas City, Mo. Hammer told the victim that they were there to shut the victim's club down, then flipped a table over knocking the victim to the ground. Once on the ground, Hammer, Crump and the other Pagan's member began stomping, kicking and punching the victim. The victim later told law enforcement that those who assaulted him were wearing steel-toed boots. Crump, Hammer and the other Pagan's member fled the bar & grill before any law enforcement arrived. The victim was later transported by ambulance to a local hospital, suffering from a head contusion (bruise on the brain), rib fracture, hemothorax (accumulation of blood in the area between the chest wall and lungs), a left pulmonary contusion (bruising of the lung), pneumothorax (collapsed lung) and a traumatic brain injury.

Hammer pleaded guilty to the assault on June 18, 2025, and is awaiting sentencing.

Under federal statutes, Crump is subject to a sentence of up to 20 years in prison without parole. The maximum statutory sentence is prescribed by Congress and is provided here for informational purposes, as the sentencing of the defendant will be determined by the court based on the advisory sentencing guidelines and other statutory factors. A sentencing hearing will be scheduled after the completion of a presentence investigation by the United States Probation Office.

This case is being prosecuted by Assistant U.S. Attorneys Bradley K. Kavanaugh and Robert Smith. It was investigated by the FBI, the Independence, Mo., Police Department, the Blue Springs, Mo., Police Department, Homeland Security Investigations, and the Kansas City, Mo., Police Department.
