Six Flags Great America released the following statement regarding the shooting:

Six Flags dedicates our greatest amount of time, talent and resources to safety and security.

Layers of preventative measures both inside and outside the park are in place for the protection of guests and team members. We continue to review and enhance our protocol on a daily basis to ensure we are providing the highest level of safety.

Cameras placed in the parking lot and inside the park, uniformed and plain clothes patrols throughout the property, and advanced screening technology allow us to react quickly and provide important information. The park security team is joined by the Gurnee Police Department, who operates a substation at the park.

This evening, we are incredibly grateful to our team members who reacted in a professional manner to take care of our guests, and for the Gurnee Police Department for their on-going presence and commitment to Six Flags Great America.

The lions were removed for a steam cleaning and wax preservative.

The lions have been a part of the museum since 1894.
