Evanston police are seeking an arrest warrant for a suspect in the Sunday shooting death of an Evanston resident at The Keg of Evanston.

Police did not give the name of the suspect but said in a press release that “there was a dispute going on” between the suspect and the victim, 22-year-old Robert Gresham of the 1300 block of McDaniel Avenue. No one has been charged yet in the shooting.

Gresham was shot dead in a fight with the suspect and at least one other man, said Deputy Chief Joe Bellino of Evanston Police Department.

The bar had a “full house” at the time of the shooting, Bellino said. Bellino said investigators don’t yet know why or how the fight started.

Several patrons started fighting just before 2 a.m. at the bar, 810 Grove St. One man shot Gresham with a handgun, police said.

Gresham of the 1300 block of McDaniel Evanston was pronounced dead of a gunshot wound at St. Francis Hospital, 355 Ridge Ave.

Evanston police and The North Regional Major Crimes Task Force are still investigating the shooting. Detectives from Evanston and 12 other north suburbs formed the task force in 1997, according to the City of Evanston Web site.

Mayor Lorraine H. Morton said she planned to suspend the Keg’s liquor license.

A woman who answered the phone Sunday at Gresham’s home declined to comment.
