A Cedar Falls man has been charged with sexual assault and transmission of the virus that causes AIDS in incidents involving at least three boys, Cedar Falls police said Friday.

Guy Dell Sudduth, 41, is accused of providing alcohol to minors and allowing drug use in his apartment, said Capt. Jeff Olson of the Cedar Falls Police Department.

"After the minors were physically and mentally impaired, Sudduth would engage in sex acts with them," Olson said. Sexual contact occurred on several occasions in 2004 and 2005, he said.

Sudduth, also known as D.J. Smith, was being held Friday in the Black Hawk County Jail on $650,000 bond.
