A doting grandfather who immigrated from Mexico to give his family a better life and two parents on a fun outing with their toddler were among the seven people shot and killed last year at a July 4 parade in Highland Park, Illinois. A 21-year-old gunman allegedly carried out the mass shooting in the leafy suburban Chicago town that, according to FBI statistics, hadn't had a murder in more than 20 years. Betsy Backes said she first met Goldstein at a local community center north of Chicago when they were both pregnant with their second children.
