Pagan’s Member ‘Navajo’ Admits to Brutal Rival Assault

KANSAS CITY, MO – A member of the notorious Pagan’s Motorcycle Club has confessed to a savage beating of a rival biker, a crime that left the victim clinging to life. Mark A. Crump, also known as “Navajo,” 55, of Lee’s Summit, Missouri, pleaded guilty today to one count of assault resulting in serious bodily injury in aid of racketeering before U.S. District Judge Greg Kays.

The brutal attack unfolded on July 20, 2023, at a North Kansas City bar & grill. Crump, along with Jarrid A. Hammer and another Pagan’s member, targeted a lone member of a rival motorcycle club. Hammer reportedly issued a chilling threat – a promise to shut down the victim’s club – before initiating the violence by flipping a table onto the man, knocking him to the ground.

What followed was a relentless onslaught. Crump, Hammer, and their accomplice allegedly stomped, kicked, and punched the defenseless victim, who later told investigators his attackers were wearing steel-toed boots. The trio fled the scene before law enforcement arrived, leaving their victim a mangled mess. Paramedics rushed the man to a local hospital where doctors diagnosed a horrifying list of injuries: a head contusion (bruise on the brain), rib fracture, hemothorax (accumulation of blood between the chest wall and lungs), a left pulmonary contusion (bruising of the lung), pneumothorax (collapsed lung), and a traumatic brain injury.

Hammer previously pleaded guilty to the assault on June 18, 2025, and is currently awaiting sentencing. Now, Crump faces a potential sentence of up to 20 years in federal prison without parole. The statutory maximum is determined by Congress, but the ultimate sentence will be decided by Judge Kays, considering advisory sentencing guidelines and other relevant factors. A presentence investigation will be conducted by the United States Probation Office before a sentencing hearing is scheduled.

This case is being prosecuted by Assistant U.S. Attorneys Bradley K. Kavanaugh and Robert Smith. The investigation was a collaborative effort led by the FBI, with crucial support from the Independence, Missouri Police Department, the Blue Springs, Missouri Police Department, Homeland Security Investigations, and the Kansas City, Missouri Police Department. This wasn’t a random act of violence; it was a calculated move by a dangerous criminal organization.

The prosecution highlighted that this case is part of a larger Organized Crime Drug Enforcement Task Forces (OCDETF) operation, aimed at dismantling high-level criminal organizations that plague the United States. OCDETF utilizes a prosecutor-led, intelligence-driven, multi-agency approach to identify, disrupt, and ultimately destroy these threats.
