The 17-year-old boy and 19-year-old woman who were shot in the parking lot of Six Flags Great America in Gurnee have been released from the hospital, police said. No one is in custody as of Monday evening.

The shooting happened around 7:50 p.m. Sunday at the theme park located at 1 Great America Parkway in Gurnee.

Gurnee Police Department Public Information Officer Shawn Gaylor said dispatchers received multiple 911 calls for shots fired.

A white sedan entered the parking lot and drove toward the front entrance of the theme park, Gaylor said.

The suspects exited the vehicle and began shooting toward another individual in the parking lot.

The suspects then got back in the white sedan and quickly fled the area.

A third victim sustained a shoulder injury and declined transport to the hospital, Gaylor said.

The two teens were transported to Advocate Condell Medical Center in Libertyville with non-life-threatening injuries.

Both were released from the hospital the same evening, Gaylor said in an update Monday afternoon.

No arrests have been made so far.

“The shooting this evening was not a random act, and appeared to be a targeted incident that occurred outside the park. This was not an active shooter incident inside the park,” Gaylor said.

The shooting occurred near the handicapped parking spots in front of the security checkpoint where guests enter the park.

Sources told Lake and McHenry County Scanner that innocent bystanders were hit, while the intended target was not hit by the gunfire. A spokesperson for the Gurnee Police Department declined to confirm the detail.

The Northern Illinois Police Alarm System (NIPAS) assisted with clearing the theme park of guests and staff.

The Lake County Sheriff’s Office and Illinois State Police, along with many other area police departments, responded to the scene.

At least six ambulances and many other fire apparatus were also called.

Some park patrons hid during the incident while others tried fleeing from the park, witnesses told Lake and McHenry County Scanner.

Jamar P. Tuazon, who was at the theme park, said that he heard gunshots and rides started to stop minutes later.

Groups of people, including Tuazon and his family, started to hide.

He and others improvised weapons and started to plan in case they encountered a shooter.

“If those shooters come, you take the kids and run, you take the kids and run,” he told a mother.

“We armed ourselves with big rocks, as big as we could find,” Tuazon said.

The group later saw two police officers and they began exiting the park.
