Jeffery Guo, who’s accused of posing as a teenager on Snapchat and sexually assaulting young girls, waived his preliminary hearing on Friday. He pleaded not guilty to all charges.

His lawyer, Tom Dickey, said he wants the chance to interview the girls who say his client sexually assaulted them.

He added he wants all of the police reports, statements, and other evidence in hand when they go to trial.

Police arrested Guo on February 14, after the parents of one of his alleged victims found out their daughter was talking with him.

The 22 year old had two Snapchat accounts, which police said he used to talk with underaged girls, send inappropriate photos to them, and convince them to meet.

Guo faces numerous charges, including rape, kidnapping, and unlawful contact with a minor.

His family was in court has he signed his waiver.

Police are asking parents to check their daughter’s Snapchat friends list for either of Guo’s accounts: JeffG124 and AdamG.
