Disability Day of Mourning is observed worldwide every March 1 to commemorate disabled individuals who have been murdered by their caregivers, particularly parents. The day was established to highlight the tragic circumstances surrounding these murders, often justified by caregiver burnout and societal perceptions of disabled individuals as burdens. The inaugural event took place in 2012, organized by Zoe Gross from the Autistic Self Advocacy Network, following the high-profile murder of George Hodgins by his mother. Vigils are held globally, where participants read the names of murdered disabled people, focusing on those killed since the last vigil. The day aims to address the disparities in how the justice system treats cases involving disabled victims compared to non-disabled individuals. Despite initial criticisms regarding its impact on parents of disabled children, the observance has gained a more positive reception over time.
