KENT, Wash. — A Kent man was convicted Tuesday on 17 federal felony counts tied to a series of armed robberies targeting marijuana dispensaries, banks, and credit unions across the Puget Sound region, federal prosecutors said.

Shannon Hartfield, 26, was found guilty following a weeks-long trial and about three days of jury deliberations, according to the U.S. Attorney’s Office for the Western District of Washington. U.S. District Judge Lauren King scheduled sentencing for Aug. 25.

Prosecutors said Hartfield led a robbery crew that carried out a string of crimes between December 2021 and June 2022, recruiting and directing young accomplices — including juveniles as young as 14 — through social media and text messages.

Authorities said Hartfield and his co-conspirators selected robbery targets, supplied firearms, and provided getaway vehicles used to flee scenes at high speeds.

The robberies included marijuana dispensaries in Snohomish, Auburn, West Seattle and Lacey. Prosecutors said the crew robbed Kushman and Have a Heart dispensaries on Feb. 17, 2022, Lucid Cannabis in Auburn and West Seattle Dispensary on March 11, and Forbidden Cannabis in Lacey on April 18.

After some members of the group were arrested and questioned in connection with the dispensary robberies, prosecutors said the crew shifted its focus to financial institutions.

On May 26, 2022, the group robbed Seattle Credit Union and Sound Credit Union, according to prosecutors. Authorities said the crew later attempted to rob a Chase Bank branch at gunpoint on June 7 before robbing a Salal Credit Union branch, where tellers were held at gunpoint.

The group was arrested shortly after robbing a Chase Bank branch in Kent on June 17, 2022, prosecutors said. Hartfield has remained in custody since then.

During closing arguments, Assistant U.S. Attorney Kristine Foerster described Hartfield as the organizer of the crimes.

“Shannon Hartfield saw robbery as a team sport — he helped recruit the players, he directed the plays, he supplied equipment, shared in the winnings and now he is legally responsible for the actions of his team,” Foerster told jurors.

Hartfield was convicted of conspiracy to commit robbery, five counts of robbery, three counts of bank robbery, one count of armed bank robbery, one count of attempted armed bank robbery and six counts of using a firearm during a crime of violence.

Jurors were unable to reach verdicts on three robbery counts and three firearm-related counts.

Federal prosecutors said the robbery counts each carry penalties of up to 20 years in prison, while the armed bank robbery conviction carries a maximum sentence of 25 years. The firearm convictions each carry mandatory minimum prison terms that must run consecutively to other sentences, exposing Hartfield to a mandatory minimum sentence of 45 years in prison.

The FBI investigated the case with assistance from multiple law enforcement agencies, including the Seattle, Kent, Auburn, Tacoma, Tukwila and Bothell police departments, as well as the Snohomish County and King County sheriff’s offices and the Lacey Police Department.
