A 17-year-old from New Jersey has been charged in connection with a hit-and-run incident that resulted in the deaths of two girls on an e-bike. The suspect, who has been identified through court records and citations, is alleged to have intentionally struck the victims, with some reports indicating he was driving at a speed of 70 mph at the time. The teen, who has a presence on youtube, had also made disturbing remarks and posted livestreams that have been described as chillingly casual in the wake of the incident.
