A Pennsylvania elementary school janitor allegedly left gifts, candy and notes for an 11-year-old girl as her "secret admirer" for a month and had more than 70 sexually explicit images of children on his phone, according to prosecutors.

Ethan Colpetzer, a 30-year-old janitor at Claysburg-Kimmel Elementary School, was arrested and charged with 75 counts of sexual abuse of children, as well as attempted corruption of a minor and copying obscene material.

He allegedly "singled out" a girl to other employees, asking for her name, and was allegedly caught by a faculty member taking photos of a student in the cafeteria, according to prosecutors in the Blair County District Attorney's Office.

After a month of receiving secret gifts, the girl left a note for her "admirer" and asked what his name was. He wrote back, "Ethan," which raised a teacher's suspicion because there were no students with that name, prosecutors said.
