The double murder trial of Darnell Williams concluded Friday with guilty verdicts in the slayings of 8-year-old Alaysha Carradine in Oakland on July 17, 2013, and 22-year-old Anthony Medearis in Berkeley two months later. As CBS 5 reports, "Emotions erupted in the Oakland courtroom filled with family and friends of the young girl."

The murder of Carradine, who was fatally shot as she answered the door of a friend's grandmother's house, where she was having a sleepover, shocked the Bay Area as a standout act of violence in what is often a tragically repetitive narrative gang-like warfare and street shootings in Oakland.

The prosecution successfully convinced the jury that Williams committed the shooting in retaliation for the murder of his friend, 26-year-old Jermaine Davis, just hours earlier. Williams had apparently concluded, along with associates, that the culprit in Davis's murder was Antiown "Twanny" York, and the house into which he indiscriminately shot was the home of York's baby mama, according to witness testimony. As the story went, the doorbell rang, the young girl answered, and Williams fired several shots into the home, killing her as well as wounding a 7-year-old girl, a 4-year-old boy, and the 63-year-old grandmother who was babysitting.

A key witness for the prosecution was Williams's then girlfriend Britney Rogers who was with Williams the night of Carradine's murder. She testified last month that she and Williams were up all night afterwards, and then saw on the news the next morning that a young girl had been killed, to which Williams responded "fuck that bitch."
