Yes, Joe Sullivan, a high-profile figure in the American legal system regarding juvenile sentencing, did use a wheelchair. Sullivan was famously sentenced to life without parole in Florida for a non-homicide crime committed when he was only 13 years old. During his decades of incarceration, his health significantly deteriorated. He was diagnosed with multiple sclerosis (MS), which eventually left him physically disabled and confined to a wheelchair. His case became a centerpiece of the legal battle led by the Equal Justice Initiative (EJI), which argued that sentencing young children to die in prison was "cruel and unusual punishment." This advocacy eventually led to the landmark 2010 Supreme Court ruling in Graham v. Florida, which banned life-without-parole sentences for juveniles convicted of non-homicide offenses. Sullivan was eventually released in 2020 after serving over 30 years, at which point he was heavily reliant on his wheelchair for mobility.
