Tarina Mitchell, 22, of Rockford, Illinois, was found dead in the front seat of an SUV on January 13, 2015, the victim of multiple gunshot wounds. The same incident left Benito Martinez lying in the street with gunshot wounds; he later died. Derrick Patterson was wounded in a nearby car and survived.

Investigators eventually identified multiple people believed linked to three separate Rockford murders, including the deaths of Mitchell and Martinez. In November 2017 authorities announced arrests of five individuals; one accused was Terrick Terell Mackey, 29, who faced charges including first-degree murder and aggravated battery with a firearm. Prosecutors indicated the cases involved complex evidence and that, if convicted, the suspects could face lengthy prison terms.

Anyone who knew Tarina, Benito, or Derrick, or who has information about the shooting on January 13, 2015, is asked to come forward.
