LISLE, Ill. (WBBM NEWSRADIO) -- Police are still looking for a motive into Friday night's shooting at a west suburban cigar lounge that killed a retired Illinois State Trooper and injured two other people.
A witness spoke to CBS 2 recalling the details of Friday night's attack.
Patrick Carlin of Naperville was inside the Humidor Cigar Lounge on Ogden Avenue in Lisle when gunfire erupted on Friday night. Lisa McMullan of Hyde Park pulled out a gun and opened fire killing one retired state trooper, injuring another and wounding an active duty state police officer.
Carlin said it was a calm night at the cigar lounge. He and his friends were hanging out, playing pool, smoking cigars, when in a nearby room, he heard a noise.
“The first one sounded like a bang; like something had fallen,” Carlin said.
But a second bang came, and then another.
“And then I think after the third shot, there was screaming,” Carlin said.
Carlin told CBS 2 that was when he and his friends left, but they came back to hear that Lisa McMullan shot three people and then shot and killed herself.
Retired Illinois State Trooper Gregory Rieves, 51, was killed when he was shot in the head.
A current trooper, Kaiton Bullock, 48, and a retired ISP special agent, Lloyd Graham, 55, were hurt in the shooting.
“They had said that this lady Lisa shot these guys,” Carlin said. “I couldn’t believe it, because I know her. Every time that I had gone to the lounge, I would say, she was there all of the time.”
Carlin said the woman always had a distinct laugh, one he couldn’t mistake that night.
Carlin told CBS 2 that McMullan appeared to be in good spirits before the shooting.
"She was laughing a half hour before this happened," he said. "That's why I just couldn't believe it."
State police said Sunday evening that Bullock and Graham were recovering and their conditions remained stable.
Investigators said McMullen knew Rieves, but they have not said how.
On Monday, police are speaking to two surviving victims to piece the crime together.
