$16 millionSettlement

Seattle Public Schools agreed to pay $16 million in October 2024 to settle a lawsuit from a former Garfield High School student who said two coaches sexually abused her over several years while the district failed to intervene. The suit named volunteer coach Walter Jones, who had been barred from district employment yet was allowed to coach anyway, and assistant coach Marvin Hall, who continued an abusive relationship with her into her college years. It is the largest tort settlement in the district's history, funded mostly through the district's insurance pool. Both coaches were separately prosecuted in King County Superior Court: Hall pleaded guilty to sexual misconduct with a minor in 2025, and Jones's child rape trial ended in a hung jury and a mistrial in December 2025. Paul Sewell and Tomas Gahan of Peterson Wampold Rosato Feldman Luna represented the former student.

$1.22 millionVerdict

Emily Daley, 42, had spinal surgery in July 2011 to correct a worsening curve from scoliosis she had lived with since her teens. Instead of straightening her spine, the operation by Dr. Michael Thomas left her with a severe forward and left lean, and Daley alleged Thomas then failed to provide adequate follow-up care. For three years she lived with pain that was at times severe enough to make her lose consciousness, until a different surgeon corrected the lean in August 2014. In July 2017, a Yakima County Superior Court jury awarded her $1,219,052, covering her past medical expenses and non-economic damages.
