Four juveniles have been arrested for the murder of a Granite City man last week.

"Investigators from the Major Case Squad have been working around the clock since the Homicide took place this past Thursday evening," according to Major Jeff Connor, commander the Major Case Squad. "Their hard work and effort led to the arrest of 4 individuals they believe are responsible for this crime."

Connor said the suspects are currently in custody. But because Monday is a holiday, they likely won't be formally charged until Tuesday.

"The four suspects that are in custody are all juvenile males, however, we believe with this type of crime 3 of them will be eligible to be charged as adults," Connor wrote in a release.

Charles A. Weiss was found shot 9:25 p.m. Thursday in an alley near the 1200 block of Meridian Ave. in Granite City. Before he succumbed to his injuries, Weiss told police that "they tried to rob me."

Weiss sustained a single gunshot would to the chest. He tried to walk away from the scene when he collapsed in the ally. Three or four male suspects were believed to be involved in the shooting. According to investigators, several suspects were interviewed about potential involvement in the case over the weekend before the four currently in jail were arrested.

Connor said police plan a press conference at 2 p.m. Tuesday at the Granite City Police Department to announce formal charges.
