NAPERVILLE, Ill. (STMW) — Bond was set at $250,000 on Monday for a man accused of stabbing a security guard in a west suburban bar early Sunday as he attempted to escort the man out.

Naperville Police said they responded to the bar at 16 W. Jefferson Ave. shortly after 1:30 a.m. Sunday for a report of a stabbing. The first officers who responded met with bar staff, who had wrestled 31-year-old Adam B. Hearn to the ground and held him until police arrived, according to police.

Hearn and his girlfriend, Kelly L. Cihlar, 25, were found in a restroom of the bar smoking a cigarette and were asked to smoke outside, a release from police said. Hearn became verbally abusive to the security staff, who then asked the couple to leave for the night, police were told. As security staff began to escort the couple out of the bar, a fight ensued between Hearn and a security guard, the release said. Hearn took a knife out from his pocket and stabbed the security guard in the abdomen, the report stated. Several other security guards arrived at the area and Hearn was subdued until police arrived, according to the release.

The security guard was treated on the scene by the Naperville Fire Department and taken to Edward Hospital in Naperville, where he underwent surgery for his injuries, police said. Information on his condition was not available Sunday night.

During the initial police investigation, Cihlar obstructed and fought with responding police units, police said. Cihlar, of the 2700 block of Mohawk Avenue in Woodridge, was arrested and charged with obstruction of a police officer, resisting arrest, battery, possession of drug paraphernalia, and possession of cannabis, all misdemeanors.

Hearn, of the 900 block of South Main Street in Lombard, was arrested and charged with aggravated battery with a deadly weapon, aggravated battery with great bodily harm, and possession of a weapon by a felon, all Class 3 Felonies, the release said. He was taken to the DuPage County Jail.

Bond for Hearn was set at $250,000 on Monday and an arraignment date was scheduled for April 4, DuPage County State’s Attorney’s office spokesman Paul Darrah said.

A judge also ordered Hearn have no contact with any gang members and ordered that he cannot possess any weapons, Darrah said.

In November, following customer complaints and police reports related to drinking and disorderly conduct, BlackFinn management said were are making changes to rein in rowdy behavior. Naperville Police Chief David Dial said at the time that a “disproportionate” number of disorderly conduct and DUI arrests had recently been made related to BlackFinn.

According to Dial, whenever a suspect is charged with DUI of alcohol, the officer asks where they had been drinking.

Naperville Mayor A. George Pradel, who also serves as the city’s liquor and tobacco control commissioner, said the commission would discuss the BlackFinn situation at a future meeting. In past situations, according to Pradel, the commission would meet with owners of the restaurant in question before calling for a formal hearing.

“We say, ‘We don’t expect this to continue and if it does we’ll have you in for a formal hearing,’” Pradel said at that time.

Contacted Sunday afternoon, Pradel said he was aware of the stabbing and called for an immediate investigation by Naperville Police. If the situation warrants, he said, he will ask the Liquor Commission to consider the issue at its next meeting in April.

Disorderly conduct issues last year included an incident in which a 26-year-old woman slapped another customer in a disagreement over a bar stool on Oct. 22, as well as an Oct. 29 incident in which another customer struck a BlackFinn security worker in the head after being escorted from the restaurant.

BlackFinn officials at the time said remedies would include “further training” of the staff in customer service, the addition of off-duty police officers to serve as security, the lowering of capacity levels on the weekends and continued cracking down on the use of false IDs by underage patrons.

Three telephone calls to BlackFinn seeking comment were not returned as of Sunday night.
