Osceola County deputies arrested Irene Miller, 50, at the airport on October 23 after a 911 call from her home on the night of October 21 reported a dumbbell had fallen on her nine-year-old son's head. Deputies found the injured boy with three siblings, ages 14, 12 and 11, unsupervised. Miller told investigators she flew to Las Vegas for work on October 18 and had arranged a babysitter from Tampa who was not required to stay overnight. She faces four counts of child neglect without great bodily harm; the children's father took custody. Coverage now centers on the five days the children were alone and on the overnight babysitting arrangement.
