RELATED: Santa Clara police arrest man accused of stalking minors
Sanhi, 35, is accused of stalking at least four underage girls but Santa Clara County investigators believe there could be a total of 19 alleged victims based on what they found at his home.
"We saw that he had a lot of photographs of these young girls, almost in a kind of a shrine on his wall, pretty serious stuff," said Santa Clara County Sheriff Laurie Smith.
Until he goes in front of a judge Thursday, there's no bail. He's facing several counts of stalking and annoying underage girls.
Detectives served a search warrant at his home on South Tantau Avenue. In addition to photos of girls, police say they found gifts including a personalized license plate intended for would-be victims.
Investigators say Sanhi had applied for jobs and volunteer positions at churches and schools and that he handed out business cards to girls promoting his website and a book called, "JC Makeover." His website is all about inner beauty and Jesus.
"It's about finding people who are potential victims," Smith told ABC7 News. "Cultivating people, trying to earn their trust."
One 14-year-old reported Sanhi followed her home on multiple occasions. A neighbor, who didn't want to be identified, told us she had an unsettling interaction with him a few months ago.
"I had to call the police on him," she said. "He was harassing some high schoolers who were walking by, shouting obscenities at girls."
Police believe Sanhi engaged in similar activity in Saratoga, Los Gatos, San Jose, and Los Altos, even following one girl to the Los Angeles area.
A mom who on the street says it's shocking. "This is an area with a good school district," said Cupertino resident Holly Peng. "It's hard to believe."
Investigators are working to locate other potential victims. They ask anyone who has had an inappropriate encounter with Sanhi to contact them and come forward.
