LITTLE VILLAGE — A 16-year-old boy shot a 24-year-old woman in early August — then shot that woman and her sister again last week, killing the sister, prosecutors said Wednesday.

The teen, whom Block Club is not identifying because he is a juvenile, was arrested Tuesday and charged with first-degree murder, aggravated battery, discharging a firearm and attempted murder. Prosecutors said he shot and wounded the 24-year-old woman Aug. 7, then shot her again and fatally shot her sister, Jezebell Perez, 22.

The Aug. 7 shooting occurred near Christiana Avenue and 28th Street, prosecutors said.

The 24-year-old woman, who had previously had a relationship with the 16-year-old, was trying to confront his new girlfriend about a Facebook post when the teen shot her three times, prosecutors said. She was hospitalized, prosecutors said.

Police were still investigating that shooting when the fatal shooting occurred about 8:20 p.m. Aug. 24 in the 2700 block of South Homan Avenue, prosecutors said.

Perez and her sister, the 24-year-old, were driving home from Walgreens around 26th Street and Kedzie Avenue with Perez’s two young daughters in the back seat, prosecutors said.

Perez was driving the car and pulled up next to a car carrying the teen, his girlfriend and another person, prosecutors said. Perez and the teen’s girlfriend began arguing about the Aug. 7 shooting, prosecutors said.

Perez threw water at the teen’s girlfriend’s car and drove away, but the two groups confronted each other again on 28th Street between Homan and Christiana avenues, prosecutors said. Perez parked her car near where the teen, his girlfriend and another person were parked, and she got out of her car, prosecutors said. The 24-year-old woman and the two kids were still in Perez’s car, prosecutors said.

Perez argued with the teen’s girlfriend, and the teen went to a nearby tow lot where a gang is known to keep guns, prosecutors said. He got a gun, came back to where Perez and his girlfriend were fighting and shot Perez four times, prosecutors said.

The teen then shot Perez’s sister while she was trying to run away down 28th Street, prosecutors said.

Perez was pronounced dead after being taken to a local hospital.

A Cook County judge ordered the teen held without bail Wednesday. He was on juvenile court supervision for a separate aggravated unlawful use of a weapon case at the time of the two August shootings, prosecutors said.

Perez did community work in Little Village and worked full-time at a bank, according to family who started a GoFundMe to cover funeral expenses. Her daughters are 1 and 4.
