Three other incidents in 2011 and 2012 involved children using the compression strap to climb into a pool—though those cases did not result in death.

Nine children under the age of five have died in pool drownings across Virginia since Memorial Day, according to the Virginia Department of Health.

Millions of above-ground pools sold at major retailers nationwide are being recalled following the deaths of nine children, according to the Consumer Product Safety Commission. Bestway, Intex and Polygroup, along with the CPSC, announced the recall of approximately 5 million pools on July 21, citing a drowning hazard.
