Man pleads not guilty to child sex assaults

RACINE, Wis. (AP) - A Racine student accused of molesting at least six young children and producing a cache of child pornography has pleaded not guilty to 49 felony charges.
 
Twenty-nine-year-old Alexander R. Richter entered his plea Wednesday after waiving his preliminary hearing.
 
Prosecutors say Richter volunteered to babysit his classmates' pre-teen children and then repeatedly had sex with the boys and girls on camera as they cried and begged him to stop. The youngest alleged victim was a 4-year-old girl.
 
Charges 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.
