Kyle Arrington, a 34-year-old man from Chicago, died on June 20, 2013, of wounds sustained in a May 15, 2013, shooting in the 9900 block of South Walden Parkway in the Beverly neighborhood. The shooting happened about 12:35 p.m. during a dispute with 29-year-old David Twine of Matteson. Arrington was shot six times in the back as he tried to flee through a glass door in the vestibule of his fiancée’s apartment building and was taken to Advocate Christ Medical Center in Oak Lawn, where he remained in critical condition for more than a month before dying. The Cook County Medical Examiner ruled the death a homicide.

Twine was arrested June 1, 2013, on aggravated battery with a firearm and held on $500,000 bond; after Arrington’s death authorities expected charges to be upgraded and an indictment was returned with a scheduled arraignment on July 5, 2013. Twine and Arrington had been friends since high school and the motive was reported as unclear to Arrington’s family.

Does anyone have information about the dispute or witnessed the incident in the 9900 block of South Walden Parkway on May 15, 2013?
