CHICAGO — A 24-year-old man was charged Wednesday with first-degree murder in the deadly shooting of a 7-year-old girl on the Northwest Side earlier this year.

The shooting occurred on the afternoon of Aug. 15 in the 6200 block of West Grand Avenue. Serenity Broughton, 7, and Aubrey Broughton, 6, were being put inside a vehicle by their mother when gunfire erupted.

Serenity was shot in the chest and torso and later died at the hospital. Aubrey was also shot in the chest, but survived the shooting.

Aireon Luster, 24, was arrested in the basement of his grandmother’s home in Riverside Wednesday, CPD Supt. David Brown said.

He has been charged with first-degree murder and first-degree attempted murder. Luster is the same suspect arrested in September, but was released when the Cook County State’s Attorney’s Office initially said there was not enough evidence to bring charges.

At the time, the district commander, along with Ald. Gilbert Villegas, criticized Kim Foxx for the refusal to bring charges. The commander wrote an internal CPD memo expressing his desire to take the case directly to a judge himself to get charges filed.

Brown said since that time, additional evidence surfaced — leading to the arrest of Luster.

Police believe the shooters were targeting a relative in the home, Chief of Detectives Brendan Deenihan said Wednesday.

Police are still asking the public’s help with locating the second shooter and the driver of the vehicle.

A $2,000 reward was offered for information leading to an arrest. Anyone with information can leave an anonymous tip at
