Two brothers, aged just 10 and 14, have turned themselves in to Philadelphia police after video allegedly captured them among a group of kids who beat 72-year-old James Lambert to death with traffic cones on June 24. Video of the incident, which went viral upon its release Friday, showed the group smiling, laughing and recording on cell phones as Lambert fled for his life. Authorities said Lambert died a day later at a local hospital from head injuries and the children fled. Police said no formal charges have been filed yet against the two brothers, who handed themselves in Monday, and their identities were not released. The other five involved—two boys, three girls—have not been arrested. Assistant District Attorney Joanne Pescatore told CBS 3 that a meeting between homicide detectives and the boys’ attorney is scheduled, and police hope to learn the names of the other children involved then.
