Massachusetts, Connecticut, and Rhode Island are considering adding symbols to license plates to make it easier to identify cars and find missing and abducted children. Magi Bish, the mother of 16-year-old Molly Bish, who was murdered in 2000, is championing the effort. Bish said she was unable to remember the license plate number of a suspicious car she saw near the pond where her daughter disappeared. “Molly's Bill” would change the license plates to have five characters with a symbol, which advocates say can be easily identified, even by a 2-year-old child.
