CALUMET CITY, Ill. — The River Oaks Mall has reopened Friday after a security guard was shot and killed Wednesday, according to the city.

According to a statement from a representative for Mason Asset Management and Namdar Realty Group, while the mall is open, tenants are required to remain close due to an order from the city and police department.

“Our team is working diligently with city officials and the police department to allow tenants to open by early next week as consumers begin holiday shopping,” the representative said.

Calumet City police said 57-year-old Norman Thomas was killed in the incident.

The three men entered River Oaks Mall, shot Thomas and stormed into Flawless Diamond Store stealing jewelry and watches.

On Saturday, Sean Howard, a spokesperson for the city, said a person of interest is in custody but no charges have been filed yet.

Thomas was an army veteran and the ‘glue’ that held everyone together, a family member said.

The representative said the mall is working with police and city counsel to assist in the investigation and “ensure the safety and security of our merchants, employees, and patrons within the mall.”

Anyone with information is asked to call police at 708-868-2500.
