Investigators are working to identify more than 100 children allegedly abused by a Delaware pediatrician, Dr. Earl Bradley, 56. Authorities want parents of Dr. Bradley's patients to provide photos to compare with videos they claim Bradley used to document his sexual abuse. Some families are struggling with whether to find out if their children are among the victims. Bradley is being held in lieu of $2.9 million bail and is charged with 471 separate crimes. If convicted, he could become one of the most notorious pedophiles in the nation’s history.
