Retired Trooper Executed, 2 Other Troopers Wounded During Cigar Lounge Attack

Lisle, IL – A recently retired Illinois state trooper was executed and two other troopers were seriously wounded when a woman opened fire on them from behind as they were watching television at a cigar lounge on Friday night.

Retired Illinois State Police (ISP) Trooper Gregory Rieves, 51, was socializing at the Humidor of Lisle cigar lounge on Ogden Avenue with off-duty ISP Trooper Kaiton Bullock, 48, and retired ISP Special Agent Lloyd Graham, 55, the Chicago Tribune reported.

They were watching a big-screen television in the lounge’s “media room” at approximately 10:10 p.m., when a woman suddenly stood up and opened fire on them from behind “without apparent provocation,” the Lisle Police Department (LPD) said.

The shooter, later identified as 51-year-old Lisa McMullan, executed Trooper Rieves by shooting him in the back of the head.

She then fired multiple rounds at the other two troopers before she turned the gun on herself, the Chicago Tribune reported.

McMullan died from her self-inflicted gunshot wound, WBBM reported.

She fired a total of seven rounds during the attack, according to the Chicago Tribune.

Trooper Rieves was rushed to a local hospital, where he was pronounced dead.

Trooper Bullock and Agent Graham were transported to local hospitals in serious condition, but are expected to recover from their wounds, Heavy reported.

They were “surrounded by loved ones” on Saturday, ISP Director Brendan Kelly told the Chicago Tribune.

“We have no idea why this happened,” Lisle Acting Police Chief Ron Wilke said of the attack, which was captured on the business’s security cameras.

Investigators said that Trooper Rieves and McMullan went to high school together in the 1980s, but it is unclear how well they knew each other.

They both were also frequent patrons at the cigar lounge, the Chicago Tribune reported.

The shooter had no prior criminal history and had a concealed carry license and a valid firearm owner’s identification card.

Trooper Rieves, a 25-year veteran of the ISP, retired from the force in March of 2019, WBBM reported.

He was “well-loved by all those who worked with him,” Director Kelly told the Chicago Tribune.

Trooper Rieves leaves behind his mother and his 23-year-old son.

“He did have a good life,” Hattie Rieves said of her son. “A life that he loved.”
