Authorities say looters shot and killed a retired St. Louis police captain early Tuesday, according to reports.

David Dorn, 77, suffered a gunshot wound to his torso about 2:30 a.m. Tuesday and died on a sidewalk in front of the looted shop, Lee's Pawn & Jewelry, the St. Louis Post-Dispatch reported. The paper reported the shooting was apparently recorded on Facebook Live.
