(CNSNews.com) – In the 20-day period of the George Zimmerman trial, four minors – three teens and a five-year-old boy - were gunned down in Chicago, according to Homicide Watch Chicago, a Chicago Sun-Times publication, which details every murder that takes place in the city.

On June 28, five-year-old Sterling Sims was killed in a double murder that also claimed the life of his mother, 31-year-old Chavonne Brown. Both were shot in their apartment, and police believe the motive was robbery.

On July 1, 16-year-old Antonio Fenner was gunned down on the sidewalk next to the body of a 32-year-old man who had gang ties. No arrests were made, and no suspects have been named. Fenner’s mother believes her son was in the wrong place at the wrong time, because no one in her family knew the other victim or what Fenner’s association was to him.

On July 3, 14-year-old Damani Henard was murdered outside a high school. His body was found next a bicycle.

On July 9, 15-year-old Ed Cooper was shot and killed while spending time with friends at the park. A gunman got out of a black van and began firing as the boys ran away. Cooper was shot in the street and continued running to a vacant lot where he died.

Zimmerman was charged with killing Trayvon Martin, an unarmed black teenager in Sanford, Fla., who was walking through a gated community on his way home from the convenience store. Zimmerman argued that he acted in self-defense.

The trial began on June 24 and ended on July 13 with Zimmerman’s acquittal.
