A man has been arrested and charged with capital murder over the killing last week of 7-year-old Jazmine Barnes in Houston, who was shot while in a car with her mother and three of her sisters. The suspect was originally believed to be a white man in a possibly racially motivated shooting, but police now say that African-American Eric Black Jr., 20, was responsible in what is likely a “case of mistaken identity.” Police say Black was driving the car from which the deadly shot came. They apprehended Black after receiving a tip from journalist Shaun King. A second suspect is thought to be in custody, but his identity is yet to be confirmed by police.
