The group, calling itself the “All Life Matters Coalition,” gathered at 12th and Jefferson Streets, where newlywed mother of two Kim Jones was shot once in the back of the head in broad daylight.

“Do not tell yourself that this kind of lawlessness is isolated,” said state representative W. Curtis Thomas (holding microphone in photo), who led the rally.  “This kind of lawlessness is like a cancer — it will grow and grow until it hits your home and hits your family.”

Philadelphia Police Department homicide unit captain James Clark, who was visiting the scene at the time of the rally, says there is no known motive for the bizarre execution.

(Kuznits:)  “I understand that Kim Jones was a social worker.  Does this have to do with one of the custody cases she was working on?”

(Clark:)  “We don’t believe so, but we’re looking at that angle as well.  We have detectives that have gone and talked to her bosses at her job.  We are looking at that as well.”

And Clark says that although a suspect has yet to be taken into custody, “They’re not going to get away with it.  We’re going to find the person responsible for this and we’re going to bring them to justice.”
