Security guard charged in shooting that killed woman, 21, at suburban Chicago nightclub

A man hired as a security guard at a nightclub in the west Chicago suburb of Stone Park was charged Monday in the shooting death of a 21-year-old woman inside the club earlier this month. 

Kevin Henley Jr., 35, of Chicago's South Side, was arrested Monday in the killing of Zulma Calderon-Pacheco. Henley was charged with one count each of involuntary manslaughter and aggravated unlawful use of a weapon, and will appear for an initial appearance at the Maybrook Courthouse in Maywood on Tuesday.

Stone Park police said Henley was taken into custody a few hours after the shooting and then released, after the Cook County State's Attorney's office reviewed the case. But he has now been arrested and charged.

CBS News Chicago has learned Henley should not even have been working at the club that night. Not only was he not licensed to work as a security guard, but police said he was not licensed to carry a gun.

Stone Park police confirmed a fight broke out inside the Mansion Nightclub, at 3801 W. Lake St, just before 1:40 a.m. Saturday, March 8. Police said the security guard pulled out a gun and fired once, hitting and killing Pacheco.

Pacheco's boyfriend said he was at the Mansion Nightclub with her Friday night into early Saturday morning, and they both saw a fight break out inside the club when a single shot hit and killed Pacheco while they were dancing.

Pacheco was the oldest of five kids. Her family said she was always helping her mom, who is now dealing with the unimaginable loss of her daughter.

Pacheco's family said video from Facebook showed the moment when a man in a black shirt and pants fired a shot during a fight. The family said the shot hit Pacheco in the chest.

CBS News Chicago reached out to the owners of the Mansion Nightclub to see if they did a background check on Henley and if he was approved to carry a weapon inside the club. There had been no response as of late Monday night.

In the wake of the shooting, a petition has been created to shut the nightclub down. Stone Park Police said in the last year, they've responded to roughly three calls per week at the nightclub, with calls ranging from ambulance assists to unwanted subjects and other disturbances.

Pacheco's family has also filed a wrongful death lawsuit against the club and the security guard.
