LISLE, Ill. — After an apparently unprovoked shooting inside a Lisle cigar lounge left a former Illinois State Trooper dead and two other law enforcement officials injured Friday, investigators are still searching for a motive in the case.

Lisle police responded to a call of a shooting at Humidor Cigar Lounge on the 1600 block of Odgen Avenue just after 10 p.m.  Friday. When officers arrived, they found the 51-year-old woman, identified as Lisa McMullan, dead and three men injured.

One of the men, identified as 51-year-old Gregory Rieves, died at the hospital. He was a retired state trooper who worked on the force for 25 years.

Police said surveillance video shows a group of people watching a big screen TV inside a media room at the bar. The woman, who was sitting behind the group stands up, pulls out a gun and shoots the 51-year-old trooper in the head. She then shoots the other two men before fatally shooting herself in the head.

Mourners offered prayers for Rieves' family during a vigil at the Humidor Cigar Lounge Sunday. Nearly two dozen gathered, and flowers were placed beneath a sign that read “may you rest in peace, Greg.” Friends exchanged hugs and held hands, as they tried to grasp what happened.

“At this point we have no idea why this happened, but certainly that will come out in the next day or so,” said Acting Chief of Police Ron Wilke, Lisle Police Dept.

On Saturday night, police released more information about the shooter, Lisa McMullan. Police said McMullan has no known criminal history and no known contact with the Lisle Police Department. They say she fired seven shots inside the lounge, including the bullet used to kill herself.

Police said McMullan and Rieves may have gone to high school together, classifying their relationship as acquaintances, and investigators are working to determine if they were more than that.  Police said Rieves and McMullan have been known to frequent the Humidor of Lisle at the same time.

McMullan possessed a valid FOID and CCL through Illinois State Police.

The two other officers who were injured are recovering at Edward Hospital and Good Samaritan Hospital. One of them is 55-year-old Lloyd Graham, a retired officer. He was hospitalized and was stabilized.

The other, 48-year-old Kaiton Bullock, was off-duty at the time of the shooting. He is a 22-year veteran of the force. Both remain in serious but stable condition.

“While whatever investigation remains to be done by the Lisle Police Dept., the Illinois State Police family is focused on the health and wellness of all who have been affected by this terrible violence,” said Brendan Kelly, Illinois State Police.

The investigation is ongoing.

A public wake for Rieves will be held Friday night at Proviso East High School from 6-8 p.m. His visitation and funeral will take place Saturday at Rock of Ages Baptist Church in Maywood from 11 a.m. to 1 p.m.
