A Vicksburg man charged by the FBI with two counts of child sexual exploitation will remain in jail after probable cause for his arrest was determined in a court hearing Thursday.

Bryan Neihaus, 21, 452 Tilton Ranch Road, was arrested by FBI agents after a search of his personal computer revealed a video of him sexually assaulting a pre-teen boy. He is being held in the Madison County Jail, said Sheila Wilbanks, spokesman for the U.S. Attorney’s office in Jackson.

Neihaus appeared Thursday before Magistrate Judge Linda R. Anderson of U.S. District Court, Southern District of Mississippi in Jackson.

A second hearing is set for Tuesday to determine if Neihaus will be allowed to post bond.

A “be on the lookout for” bulletin was issued in Warren County prior to his being located and arrested Jan. 29 in Tunica.

Another Vicksburg man, John Crumpler, 2957 Mount Alban Road, has also been charged with two counts of sexual exploitation of a minor resulting from the same investigation.

A complaint from an unidentified source was filed which led the FBI to serve a search warrant at the home of Crumpler.

The FBI’s investigation extended to examining Neihaus’ personal computer, which revealed numerous videos and images of child pornography including videos of both Crumpler and Neihaus with pre-teen children, authorities said.

Neihaus lived in Crumpler’s home for a period of time, an FBI affidavit states.

Crumpler also remains in the Madison County Jail in the custody of U.S. Marshals. His detention hearing Feb. 2 resulted in no bond being set.
