Seattle Man Sentenced to 17 Years for Violent Robbery Spree

First Assistant U.S. Attorney Neil Floyd stressed the pattern of exploiting minors. He stated, “This defendant recruited juveniles to do his dirty work, perhaps in the mistaken belief that it would insulate him from criminal responsibility; clearly, it did not. His actions caused terror for store clerks and bank tellers and cost one young man his life. A 17-year federal sentence is needed to protect the public and hold him accountable.”

W. Mike Herrington, Special Agent in Charge of the FBI Seattle field office, detailed how the operations unfolded: “For almost six months, Miller-Jimerson and his armed co-conspirators stormed through businesses around the Puget Sound region. By recruiting vulnerable children, arming them, and training them to commit dangerous crimes, Miller-Jimerson and another adult co-conspirator sought to minimize their own criminal liability while they shared in the proceeds, including tens of thousands of dollars of stolen cash. 

This conduct was epitomized on March 19, 2022, when Miller-Jimerson waited in a vehicle outside as an employee of a marijuana dispensary in Tacoma, Washington, lay dying, shot by a 15-year-old co-conspirator during a robbery gone wrong. This sentencing sends a clear message: adults who exploit juveniles to act on their behalf will be targeted for federal prosecution. Together with our partners, FBI Seattle will continue to combat violent crime in its many forms.”

Co-conspirator Shannon Hartfield was convicted in May 2026 on 17 federal felony counts related to the bank robberies.

Miller-Jimerson’s 17-year federal sentence will run concurrently with a 15-year state sentence handed down in Pierce County Superior Court. Judge King also ordered five years of supervised release and recognized the victim’s resilience.

“The defendants not only stole marijuana and the victim’s tip money, but they also left the victim with lasting emotional consequences. Many of these individuals continue to cope with fear, anxiety, and the disruption to their lives caused by the defendants. The impact of these crimes is likely to remain with the victims for years to come…”
