Sioux Falls resident James Kooima, 46, was arrested on Wednesday and charged with eight counts of child pornography following an investigation that began with a cyber tip received by a detective on Jan. 29.
The tip, from the National Center for Exploited & Missing Children, led to the discovery of a Snapchat account allegedly used to send or receive child pornography images.
Kooima was arrested at his residence on E. Benson Road and is expected to appear in court on Thursday.
Further charges are possible as the investigation continues.
