A search warrant was executed on the residences of Greg Stephen in Monticello and Delhi as police investigate whether the former Iowa Barnstormers AAU basketball coach took video recordings of his players without their knowledge. The search warrant was served after a source gave police an electronic device containing child pornography that was obtained from Stephen’s residence in Monticello and examined by law enforcement agents. “The affidavit states the device was found to contain video clips believed to depict young, non-adult disrobed male individuals,” it says in a release from the Iowa Department of Public Safety.
