Deangelo Antonio Burgess, a 20-year-old African-American man, was shot in the Baden neighborhood of St. Louis on the evening of Thursday, November 14, 2013, and died of his wounds at a local hospital the next day. Police found Burgess on the 4700 block of Hammett Place with a gunshot wound to the head; another account said he sustained multiple gunshot wounds.

Three men in their twenties told investigators they had been approached by Burgess, who was with several others reportedly armed; the three men fled and then heard gunfire. Investigators were unable to identify a clear motive or suspects in the immediate aftermath, and there have been no public announcements identifying any arrests or suspects.

Who knew Deangelo or was in the area that night and might have information that could help resolve this case?
