Marvin Walker Jr., identified as the boy’s uncle on a GoFundMe page, calls 11-year-old Amir Atkins “a beacon of light in our lives – a joyful, loving child whose laughter filled our hearts. He had a unique spark that touched everyone he met, and his absence leaves a void that can never be filled.”

Investigators say the shooting happened while vehicles were driving through the park, though the exact circumstances and how many people were involved are unknown.
