What was supposed to be a day of national celebration turned into a day of tragedy and fear when a gunman killed seven people and injured dozens of others at a July Fourth parade in Highland Park, Illinois.

In total, about 45 people were injured or killed in the shooting, according to the Lake County Sheriff’s Office, reported by CNN.

Now, yet another community in America is grieving the loss of family and friends: Among them, the parents of a 2-year-old boy.

Irina and Kevin McCarthy, aged 35 and 37, were identified by the Lake County Coroner’s Office Tuesday. Their son, Aiden, was found alive and taken to safety in the aftermath of the violence, the family told CNN.

Katherine Goldstein, 64, of Highland Park; Jacquelyn Sundheim, 63, of Highland Park; Stephen Straus, 88, of Highland Park; and Nicolas Toledo-Zaragoza, 78, of Morelos, Mexico, were the four other victims identified. A seventh victim died at a hospital outside of Lake County, according to the Coroner’s Office.
