(Melissa Phillip / Houston Chronicle / AP) The Texas authorities have accused a man of fatally shooting a black 7-year-old girl whose death attracted national attention and chased a manhunt for the killer. In a statement at the beginning of Sunday, the Sheriff's Office of the Harris County announced that the 20-year-old Eric Black Jr. was accused of murder in the death of Jazmine Barnes. He was identified as a suspect on the basis of a tip, the police said, adding that Black later admitted that he was involved in the shooting. Researchers hunt for leads that could lead to more suspects being charged. The break in the case comes a week after Jazmine was killed in Houston while driving a car with her three sisters and her mother, LaPorsha Washington. An archer opened fire on the vehicle on December 7 on December 7, wounding Washington and injuring Jazmine lethally while dropping glass at the girls. The police said in the statement that they do not think that the family of Jazmine was the intended target and that they might have been shot at by "due to a wrong identity." "All the evidence collected so far in the Jazmine Barnes Homicide case supports the strong belief of researchers that they and her family were innocent victims," the Department said. tweeted Sunday. The death of Jazmine was partially disclosed through the efforts of activist Shaun King, lawyer-lawyer Lee Merritt, who represents the family, and numerous celebrities. Merritt and King offered one $ 100,000 reward for information that leads to the arrest of the suspect, and King has continuous tweeted updates in the case of its 1.1 million Twitter followers. Many, including Merritt, speculated that the crime was racially motivated on the basis of early witness statements by the suspect – described by the authorities as a "skinny white man" in his thirties or forties. The police in their statement did not immediately identify Black as the suspect. Merritt also identified the 24-year-old Larry Woodruffe as the second suspect in the case, although the police did not mention him. Merritt told The Washington Post on Sunday that he believes that Woodruffe is also black. "The family is still very grateful that law enforcement seems to have identified the shooter," Merritt said. "All information until yesterday, however, was that the shooter was an older white man in a red truck, which not only came from one of the victims, 15-year-old Alexis, but from an eyewitness in the neighborhood." "We had at least four independent witnesses who believed that the shooter in this situation was a white man … to learn that it was not is not disappointing, but it is surprising." Alexis Dilbert, the 15-year-old sister from Jazmine, told ABC 13 in Houston after the shooting that she saw the face of the shooter. Washington, the mother, told reporters that the shooter was a white man with blue eyes that was so thin that he looked "sick". Officials also brought one video of a red pickup that they thought the gunman was driving. [A black 7-year-old’s slaying has Houston on edge.

Although it was not immediately clear what & # 39; new direction & # 39; meant, the police said they would hold a press conference on the case on Sunday afternoon. On Saturday, hundreds of people gathered at a Walmart near the street where the shooting took place to fight for Jazmine. The demonstrators, according to the Associated Press, called themselves soldiers in an army camp on behalf of the murdered girl in a constant outpouring of support for her family. Some used characters that said "Justice for Jazmine," the hashtag used by lawyers and police to announce the murder. Earlier this week, Houston Texans wide receiver Deandre Hopkins has written a tweet that he was planning to donate his check for Saturday's playoff game to help the Jazmine family with funeral expenses. A GoFundMe set up for expenses related to the death of the girl had collected more than $ 77,000 on Sunday morning.

Harris County Sheriff Ed Gonzalez said in a statement that he was grateful to those who gave tips and assistance in their "work to get justice for Jazmine."
