RACINE, WI (WTAQ) - Police think there are more victims out there involving Wisconsin college student Alexander R. Richter.

The 28-year-old Racine man is accused of having intercourse with six children, all between the ages of 5,7,8,12 and video-taping the assaults.

Richter has been charged with nearly 50 felony counts of 1st Degree Sexual Assault, Child Sexploitation, and Possession Child Pornography.

Richter attended Gateway Technical College.

Investigators say he would volunteer to babysit the children of his classmates. He then repeatedly had sex with the boys and girls on cameras as they cried.

Videos and photographs were found in Richter’s home.

He has a preliminary hearing set for Wednesday.

Detectives say when they served a search warrant last week, Richter told them he would save them some time and directed them to look under his coffee table.
