A 26-year-old man from Rapid City, S.D., was arrested in Buffalo today on child pornography charges, according to U.S. Attorney William J. Hochul Jr.

Jesse Adams faces a detention hearing at 10:30 a.m. next Thursday before Magistrate Judge Leslie G. Foschio. Hochul said Adams, if convicted as charged, faces a mandatory prison term of between 5 and 20 years and a fine of $250,000.

An undercover investigation began in Utah when an agent there received emails and images depicting child pornography. Adams was a student in Utah.

According to the criminal complaint, Adams, in chats with the undercover agent, spoke about a nine year old girl and another young child he met on a playground.
