Two days after he was pulled from the bottom of a swimming pool at a Disney resort in Florida, a 13-year-old boy from Missouri has died.

Anthony Johnson passed away Tuesday morning, according to the Orange County Sheriff's office. No cause of death was given.

"We are saddened by Anthony Johnson's passing and our hearts go out to his family, friends and loved ones," a statement from Disney said. "We have reached out to his family to offer care and assistance during this difficult time."

The boy was swimming at Disney's Pop Century Resort pool on Sunday evening with family members and other guests when he was spotted in about 4 feet of water by a cousin, who pulled him out, sheriff's deputies told CNN affiliate WKMG-TV. Lifeguards were not on duty at the time of the incident.
