On Tuesday, August 8, 2006, at 10:55 p.m., a local law enforcement evidence technician reports to dispatch that something is hitting the walls of his trailer. He wants an officer to investigate. He is not able to do it himself as he has his family in the trailer with him. The officer arrives at the trailer and finds nothing unusual.

This incident happens about a fourth of a mile east of Sharps Corner, which is about 30 to 40 miles northeast of Pine Ridge, South Dakota.
