A 19-year-old woman was critically injured during a shooting outside on Lake Shore Drive Sunday afternoon, according to police and photos posted to social media.
The incident took place at approximately 1:20 p.m. in the 300 block of South Lake Shore Drive, the Chicago Police Department said.
Officials said the woman was inside a white Dodge Caliber traveling northbound on Lake Shore Drive at Jackson when another vehicle pulled up at a stop. Police reported "some type of conversation then occurred" between the two which led to an individual in the rear of the other vehicle to fire shots into the Dodge Caliber.
The woman's vehicle drove further north on Lake Shore Drive, then exited and stopped in the 600 block of East Grand Avenue where police were called.
Police initially said the shooting occurred in the 600 block of East Grand Avenue, which is Chicago's Navy Pier, but later updated with the new location.
Matthew Dabul-Frels, a waiter at nearby Casa Margarita restaurant, described a chaotic scene in the moments following the shooting.
"We just saw like 30 squad cars come flying down Lake Shore Drive, up toward Grand Avenue, up and down Illinois," he said. "Down here, we rarely see anything like this. I mean, this is a shock."
After arriving on the scene, officers reported the woman had been shot in the head and treated with a first aid kit. The 19-year-old was taken to Northwestern Memorial Hospital in critical condition.
Police continued to search for the suspect Sunday night.
