The shots were fired from a vehicle, which then fled “immediately” after the shooting, said Rachel Kendziora, the park’s communications specialist.
Rescue workers immediately rescued 2 people and sent them to the hospital. A third injured person refused treatment, Kendziora said.
“Park security personnel and officers from the on-site Gurnee Police Department substation responded immediately,” Kendziora said. He said both Gurney police and the Lake County Sheriff’s Office handled the scene Sunday night.
“There is no indication at this time that he is an active shooter,” Lake County Deputy Chief Christopher Covelli told CNN.
The park was closed early in response to the shooting, Kendziora said.
Gurnee is an hour’s drive north of Chicago.
Michael Pontrelli and his family were at the park when the shooting happened. He told CNN he got off the Superman ride when he saw groups of people running from the entrance.
“Then we saw (a) parents locking their children, so my family and I were waiting for permission between these two walls,” he said. “The police ran in with weapons and took everyone out.”
A video captured by Pantrelli shows a heavy police presence outside the park.
In a statement, Kentgiora said the park would like to thank the team members who worked to take care of guests and the Gurnee Police for their continued security presence at the park.
“Six Flags devotes a great deal of our time, talent and resources to safety and security,” the statement said. “There are layers of preventative measures in place inside and outside the park for the safety of guests and team members. We review and improve our protocols on a daily basis to ensure we provide the highest level of security.”
