OAKES (NewsDakota.com)- A preliminary hearing is scheduled for August 7 in Dickey County District Court for an Oakes man charged with a felony count of luring a child by computer or electronic device.

A criminal complaint filed last week alleges 33 year old Ryan Lee Marthaller sent messages to a 13 year old girl in late June asking for nude photos, then sent sexually explicit messages while again asking for nude photos.

Marthaller and his attorney Lucas Wynne attended an initial court appearance in Ellendale Tuesday morning.

The Oakes Police department is in the process of further investigating, and asking for anyone who may have been contacted by Marthaller to call their office at 701-742-2172.
