On Halloween night 2016 in the Russell neighborhood of Louisville, Kentucky, 29-year-old Brandon L. Jordan-Corcoran was shot and killed around 8 p.m. He was found at the intersection of 28th and Market streets with multiple gunshot wounds and died at the scene; residents reported hearing as many as a dozen gunshots. The coroner ruled his death a homicide.

Brandon’s family had endured a similar loss before: in 2006 his 17-year-old brother Brad Corcoran was also shot and killed, a death the family described as accidental. The family has suggested Brandon’s killing may have been retaliatory, but no arrests have been announced and no suspects have been publicly identified. Investigators say the probe has gone cold amid few leads and limited witness cooperation, though the case remains open and active.

If anyone saw activity near 28th and Market on Halloween 2016 or has information that could help Brandon’s family and investigators, please come forward.
