Sircie Varnado, a 46-year-old mother of five, was reportedly shot and killed last Wednesday (June 12), at a Chicago-area Walgreens by a man described as an “unofficial security guard.”

According to CBS Chicago, Varnado was on her way to visit her boyfriend and decided to stop by to pick some things up from the pharmacy chain when a store clerk confronted her and accused her of shoplifting.

The clerk then called a friend for assistance. That friend arrived with a gun and identified himself as a police officer.

A verbal argument ensued, which led to a physical struggle. The unidentified man shot Varnado in the head, killing her, before he fled the scene.

“She didn’t deserve to be executed like that,” Varnado’s sister, April Reed, told CBS Chicago.

“He could have just held her for the police. He didn’t have to shoot her in her face. She didn’t have no weapon.”

According to ABC 7 Chicago, officials are considering the man an “unofficial security guard” at the Walgreens and have reportedly been in contact with him.

On Wednesday, he was reportedly questioned by police and this is not the first time he’s posed as an officer. Last summer, he was accused of threatening a woman while once again claiming he was a cop.

Police say the man has no connection to law enforcement, while Walgreens says they do not have a security guard at that location.

No charges have been filed in the case as of today (June 20).
