Racine, WI -- A Wisconsin college student accused of molesting six young children and videotaping the assaults under such titles as "Monster Unleashed" has pleaded not guilty to 49 felony charges.
Twenty-nine-year-old Alexander R. Richter, of Racine, entered his plea Wednesday after waiving his preliminary hearing.
Prosecutors say Richter volunteered to babysit his classmates' children and then repeatedly had sex with the boys and girls on camera as they cried and begged him to stop.
Charges against Richter include possession of child porn and first-degree sexual assault of a child under 13.
Investigators say they've identified six children in videos and photographs recovered from Richter's home. They say they believe there are additional victims, but aren't saying how many.
A message left with Richter's defense attorney wasn't immediately returned.
