In the Pahrump Valley Times profile, Coyner says he dreamed of attending an Ivy league school like Harvard and that he wanted to become a hedge fund trader.

Police say they found a flat-screen television, allegedly stolen from a local Wal-Mart, and equipment for making fake driver's licenses in Coyner's dorm room, which he shared with Matthew Miller, 19. Miller is also charged in the case.

A third man, Nicholas Ramoser, also 19, has been charged, along with 10 juveniles, police said.

The Nye County Sheriff's Office believes it has arrested everyone whose grades were changed, but it is still investigating the matter, Boruchowitz said. "We're confident that there were others who knew about it," he added.

Coyner could not be reached for comment Friday, and Pahrump Valley High School Principal Max Buffi did not reply to a message seeking comment.
