On July 4, 2015, 28-year-old Joshua Fox was shot once in the chest and killed inside a North Knoxville home on Atlantic Avenue. He was in a back bedroom when the fatal shot occurred. Witnesses reported hearing an argument between Fox and his ex-girlfriend, 36-year-old Catalina Davila, just before the gunfire, and they saw Davila leave the bedroom holding a silver handgun.

Investigators found threatening statements Davila had posted on social media in the days before the shooting. Davila later pleaded guilty to second-degree murder and received a twenty-year sentence in the Tennessee Department of Correction; she will be required to serve a substantial portion of that term before parole eligibility.

If anyone knew Joshua, Catalina Davila, or was in the area that day, does any detail stand out that hasn’t been shared publicly?
