For the fourth time in six weeks, the Florida Department of Children & Families is investigating the death of a child who, only weeks or months earlier, had drawn the attention of agency administrators, reports the Miami Herald. The latest to die is Ezra Raphael, 2. Police say they were “summoned” to his home last Thursday to check on a “sick and unresponsive child.” He died at a hospital, and the medical examiner’s office ruled it a homicide. He had been left alone with his mother's boyfriend, a man with a lengthy arrest record. Ezra's death comes at one of the most troubling times in the agency's history: Since May 16, at least four small children have died. In the first case, the agency chose not to act last November after the mother of 5-month-old Bryan Osceola was found passed out drunk – with her car's transmission in drive – while her infant was left unrestrained in the front seat. On May 16, Bryan baked to death in his mother's car.
