Two boys, ages 2 and 3, drowned Wednesday in a backyard pool in Belle Glade. The Palm Beach County Sheriff’s Office did not identify the boys, who doctors at Lakeside Medical Center declared dead. The boys had been playing in the screened-in back porch of a home near Glades Day School when the family member watching them noticed they were missing. The family member searched for them for 30 minutes, then called for help. A PBSO helicopter spotted the boys in a nearby pool. The sheriff’s office said its investigation into their deaths remains open.
