The father of a 7-year-old Texas girl who was gunned down in front of her family in a Walmart parking lot on Sunday has made a public appeal for help in finding the man responsible. The father, Chris Cevilla, passionately spoke about his daughter Jazmine Barnes in a press conference on Monday. “I'm asking, from the bottom of my heart, anyone who knows anything please step up and help me and my family get justice for my baby girl.” Barnes was fatally shot Sunday morning while riding in a car with her mom and three sisters. The Barnes' family is black and the suspect, who police say pulled up next to the family's car and opened fire, is described as a white male in his 40s. Cevilla described his daughter as, “loving, caring, very passionate with people, sweet, just an innocent young girl... a lot of things that have been robbed of me and my family at this moment, that we will never be able to get back.”
