Where is Highland Park? What we know about Chicago suburb grieving after parade shooting.

Six people were shot and killed Monday morning at a Fourth of July parade in Highland Park, Illinois, an affluent Chicago suburb known for its picturesque homes and tree-lined streets.

About 25 miles north of Chicago, Highland Park is home to about 30,000 people and is known as a family community where several movies were filmed in the 1980s, including "Ferris Bueller's Day Off" and "Sixteen Candles."

The annual Fourth of July Parade hasn't been held since 2019 due to the pandemic. It was scheduled to begin with a parade for children and pets, followed by a larger parade hosted by the city and park district. But authorities say a gunman opened fire, apparently from a rooftop, on the parade route around 10:15 a.m. local time Monday.

“Our community is never going to recover from this wound,” Mayor Nancy Rotering said Tuesday on "TODAY."

“It’s one of those unique things about my hometown, that people come back to raise their children, their grandparents are with them. This is an absolutely devastating blow to all of us.”

Some neighbors and residents described Highland Park as having a large Jewish community, representative of a significant Jewish population in the northern suburbs of Chicago at-large. U.S. Census data from 2020 does not break down religious affiliation demographic data for the suburb. For example, North Suburban Synagogue Beth El in Highland Park serves about 1,100 families as of 2022, its website says.

In nearby Glencoe, Ill., one of the July Fourth shooting victims, Jacki Sundheim, was a congregant and staff member at North Shore Congregation Israel.
