David Terrell Davis was 27 when he was shot to death in an alley in St. Louis on November 19, 2010. He suffered fatal gunshot wounds to the head and torso and was pronounced dead at the scene. He left behind three children and a grieving family; his homicide remained unsolved.

Eleven days after Davis’s killing a second outbreak of violence occurred at his funeral service at Reliable Funeral Home. A dispute inside the mortuary spilled into the street and gunfire erupted, sending people inside the chapel diving for cover as bullets struck the building. Two 31-year-old men, Jason Finney and Trevlan Glass, were found dead and a 35-year-old man was critically wounded; police at the time were unsure whether those three were victims only or had been participants in the exchange.

Investigators suggested the funeral shooting may have been gang-related and possibly tied to Davis’s unresolved murder. After the disruption Davis was buried with undertakers and a police escort present. Who has information that could help solve David Davis’s killing?
