Chicago gun violence this weekend claimed the life of a young woman who only a few weeks ago testified against her cousin’s accused killer, according to reports.

Treja Kelley’s family suspect the 18-year-old's murder may be connected to her testimony, which helped prosecutors obtain a conviction.

“I feel in my heart of hearts that that might be the case,” Kelley’s grandmother, Judy Fields, told the Chicago Sun-Times on Monday. “But we don’t know for sure.”

Police say a man emerged from an alley and shot her multiple times, according to the station.

A jury heard Kelley testify in June against Deonte Davis, who was charged with killing Kelley's 17-year-old cousin Christopher Fields in a 2016 drive-by shooting, prosecutors said Tuesday.

Davis was found guilty after Kelley testified she witnessed the murder.

Fields said the family feared for Kelley’s safety after she testified, the Sun-Times reported.

“We were doing what we could to transport her every place she went,” Fields said. “Normally, [Kelley] would take an Uber home from work, but I don’t know why she didn’t.”

The paper quoted Chicago police spokesman Anthony Guglielmi as saying that detectives working the Kelley homicide were “investigating all possibilities” as they try and come up with a motive.
