The search uncovered collages of the victims, gifts for the victims as well as a personalized license plate for a victim, deputies said.

The investigation into Sanhi began when a 14-year-old girl said she was repeatedly approached by an adult male on multiple occasions offering her gifts of money, show tickets, and other items. The male was later identified as Sanhi.

Deputies said the minor reported Sanhi had followed her home over a dozen times and that a family member had previously confronted Sanhi, but that he continued to follow and harass the girl.
