Asher Sullivan, the storm-injured son of Rutherford County Schools Director James “Jimmy” Sullivan, died Saturday, his father announced.

“Asher officially passed away (Saturday) afternoon around 1:20 pm. I say officially because of the events of the last 36 hours,” Sullivan posted late Saturday night.

Asher had been at Monroe Carell Jr. Children’s Hospital at Vanderbilt since May 8. The 10-year-old boy was critically injured that date after being sucked into a storm drain. Before he was injured, Asher was playing with other kids in the water that had accumulated in the street while neighbors gathered to begin the cleanup process after severe storms moved through Middle Tennessee. He somehow “got caught in the storm drain and was swept under the neighborhood streets,” Sullivan previously wrote on social media.
