A Santa Clara County prosecutor filed additional charges Wednesday against a San Jose man who was arrested in San Jose last month.
Meanwhile, police called a news conference for Thursday to plead with the public to help find more victims, who may range into the hundreds.
Deputy District Attorney Steve Fein said the new charges against Dean Arthur Schwartzmiller involve a second victim. Last month, Schwartzmiller, 63, was charged with one count of aggravated sexual assault on a child under 14 after the parents of a 12-year-old boy came to police with evidence he molested the youth.
A police statement announcing the arrest said that Schwartzmiller had befriended two boys with gifts, invited them to his house for video games and movies, and molested them.
The new charges are six counts of lewd and lascivious conduct on a child under 14, with each count alleging multiple victims, said Deputy District Attorney Steve Fein. Those charges, combined with the earlier charge, could send Schwartzmiller to prison for up to 105 years to life if he is convicted.
Schwartzmiller's attorney, Deputy Public Defender Irma Gallardo, could not be reached for comment.
Schwartzmiller, who was arrested in Washington late last month and is now being held without bail in the county jail, is also wanted in Oregon on felony sexual assault charges involving a minor.
When San Jose police raided Schwartzmiller's home last month, they found the names of hundreds of children in logs, with codes that investigators believe signify ``certain things that were done to the children,'' Fein said. The victims, he said, were almost exclusively young boys.
Lt. Scott Cornfield of the San Jose Police Department said the Thursday news conference can help with one of the problems in finding victims: that Schwartzmiller used numerous aliases to throw off witnesses.
``We want his picture out there so that even if they don't know him by that name, they'll recognize his face and come forward,'' Cornfield said.
He said Schwartzmiller may have met and befriended some of his victims while working as a home remodeling contractor.
