The first thing officer James Avery saw was a 1-year-old gunshot victim being carried away in a blood-soaked towel.
Then came the screaming.
Avery rounded a corner inside the College Hill Courts apartment on Jan. 7, 2015, and found a woman, Bianca Horton, crying over a woman's body. "Who are we looking for?" the officer asked. "Who shot her?"
Horton, 26, didn't answer, and her friend, Talitha Bowman, never will.
Hamilton County prosecutors opened a 2015 murder trial Wednesday with the 11-minute body camera footage Avery took on scene that night. It's one of the many pieces of evidence they believe will convict Cortez Sims, 19, of first-degree murder, attempted first-degree murder, and employing a firearm during the commission of a dangerous felony, in the homicide of 20-year-old Bowman.
Sims, then a 17-year-old member of the Athens Park Bloods, was motivated by a yearlong feud between his gang and a rival group, prosecutors say.
