Ten teenagers between the ages of 13 and 17 are facing murder charges after beating a 17-year-old high school student to death in an alleyway near their Las Vegas high school. The fight broke out over a pair of headphones and a vape pen, but the victim was not originally supposed to be involved. The deadly beating was captured on video and shared on social media. Eight of the students have been arrested, while the identities of the remaining two are still unknown. The case is being closely examined to determine the level of culpability for each defendant.
