Chicago Police Superintendent Garry McCarthy says the outbreak of violence the city saw over the weekend is intolerable and his department is working to fix it.
McCarthy calls the issue a "day-by-day, minute-by-minute struggle." He told WFLD-TV that 75 to 80 percent of the shootings in Chicago are the result of gang violence and the availability of firearms is also an issue.
McCarthy adds that Chicago's gang problem goes back decades so it can't be fixed overnight.
His comments come after eight people were killed and at least 40 wounded over the weekend.
Police say the deaths include two people shot when someone opened fire at a party in the city's Back-of-the-Yards neighborhood late Sunday. The other victims include a 16-year-old boy who was shot outside his home Saturday.
