WATCH 52 shot in one weekend in Chicago

Less than a month into the first term of Chicago's newly elected Mayor Lori Lightfoot, the city is experiencing a second straight weekend of gun violence.

Since Friday, at least three people have been killed in shootings and more than 30 others have been wounded, according to the Chicago Police Department. One of the youngest victims was a 12-year-old boy, who was seriously injured after being shot in the back on Saturday afternoon.

This comes just a week after the city's most violent weekend so far this year, which left 10 dead and 52 wounded in shootings.

Lightfoot, who was sworn in as mayor on May 20, and Chicago Police Department Superintendent Eddie Johnson have made tackling the city's crime rate a top priority.

During the first weekend of June, the city experienced an outburst of shootings due to gang-related incidents. The violent outburst came just hours after the department announced a sharp decrease in crime on Friday.

Data collected by the Chicago Police Department from the first five months of this year showed a 13% decrease in shootings and a 7% decrease in murders compared to a year ago.

Police said 41 people were shot and seven were killed in the city just two weeks before.

More shootings are often reported in warmer months, when large numbers of people tend to congregate outdoors.

Chicago residents were told they should expect to see a "heavy" police preference this past weekend.

"While we don't comment on specifics in terms of officer deployments, we have positioned saturation and tactical teams in areas of the city that we are addressing ongoing gang conflicts that are contributing to recent violence," Chicago Police Department Chief Communications Officer Anthony Guglielmi told ABC News.

"Additionally, there will be heavy saturation patrols along Lake Shore Drive and major thoroughfares beginning Friday and through the weekend. Supplemental summer patrols were also deployed in neighborhoods across the south and west side of the city," Guglielmi added.

Detectives have already made one arrest in connection with shootings that occurred Saturday, and there are also several initiatives underway citywide to address the proliferation of guns, police said.

Since Friday, at least 14 people have been arrested on illegal gun charges and 43 weapons have been seized.

On the day of her inauguration last month, Lightfoot, a former federal prosecutor who is the city's first black female mayor, said there was "no higher calling than restoring safety and peace in our neighborhoods," according to the Chicago Tribune.

"Enough of the shootings. Enough of the guns. Enough of the violence,” the newspaper quoted her as saying.
