CHICAGO -- A Chicago police sergeant is under investigation after he showed up at the scene of a fatal shooting over the weekend while off duty and was forcibly led away by officers.
"You're gonna cuff me? You're gonna (expletive) cuff me?" the off-duty sergeant protested as officers grabbed his arms and walked him toward a police car after the shooting on Lower Wacker Drive around 3 a.m. Sunday.
The sergeant repeatedly stated his name, rank and badge number and referred to the police district where he works. "You know who I am, right?" he asked the officers.
Anthony Guglielmi, a spokesman for the Police Department, confirmed in an email that an off-duty sergeant got into an "altercation" with officers on the scene and may have been drunk.
"The off-duty sergeant had no involvement in the investigation and got into an altercation with First District personnel after he attempted to enter the crime scene area," Guglielmi said. "Alcohol may have been a contributing factor. The specifics of what transpired are now under investigation by internal affairs."
The department's internal affairs division is conducting an investigation into whether the sergeant violated any rules. Officials were not naming the sergeant because of the pending investigation and because no charges have been filed, Guglielmi said.
"Every member of the Chicago Police Department is held to the highest standards both on and off duty," he said.
The shooting in the 500 block of East Lower Wacker Drive claimed the life of Mario A. Guerrero, 24.
Witnesses told police Guerrero was driving a gray Chevy north on Lake Shore Drive when he stopped at a light at Wacker and a dark SUV playing loud music pulled up. Someone in the SUV began yelling and one shot was fired, hitting Guerrero in the chest. Two more shots rang out before the SUV sped off.
Two teens on their way home passed Guerrero's car and heard people crying for help, so they turned around. "It felt like the best thing to do," said one young man, who didn't want his name published.
