Odell Branch Sr., a 77-year-old church deacon, was killed on March 9, 2015, in Chicago’s Roseland neighborhood. He was sitting on a couch with his 5-year-old great-grandson when gunfire from an apparent gang-related exchange tore through the home. Branch was struck and died at the scene; his great-grandson was grazed. A 34-year-old woman and her 2-year-old son, who were outside at the time, were also hit — the toddler critically injured and the woman in stable condition.

Authorities say the shooting began about 6:30 p.m. after Branch’s wife, Irene Branch, returned from the store. Police believe the attack stemmed from a confrontation between rival gangs and that a teenage grandson, who may have been involved with one gang, was the intended target. Several people were detained for questioning but no charges were filed immediately.
