LAS VEGAS (KLAS) — Two teens accused of intentionally hitting and killing a bicyclist and then fleeing the scene made an initial appearance in a Las Vegas courtroom Thursday to face murder charges as adults in a crime that has captured national attention.

Jesus Ayala, 18, who was 17 at the time of the alleged crime, and Jzamir Keys, 16, are facing murder charges for targeting 64-year-old bicyclist Andreas “Andy” Probst and capturing on video the moment they swerved to hit him from behind, Las Vegas Metropolitan police said.
