Just three days since fall classes resumed following summer break, Schurz High School in Old Irving Park on Chicago's northwest side went into lockdown Wednesday after four people -- three tens and one adult -- were shot while sitting on the patio of a ice cream shop across the street from campus, police say.
According to authorities, one of the teens shot, a 15-year-old male, remains in critical condition.
"To be a child and not feel safe in their own school, that's awful," one neighbor said. "I've lived here my whole life. My dad is a retired police officer. We love the city and we don't want to leave, but where do you feel safe?"
As students and staff return to school Thursday, they'll be greeted with breakfast from the Chicago Teachers Union, along with more patrols from Chicago Police. But according to authorities, no suspects are in custody and an investigation is still ongoing.
Here's what we know.

Authorities say the incident took place just as classes at Carl Schurz High School were letting out for the day.
