A St. Paul man posing as an acting teacher was charged Wednesday for the fourth time on allegations that he molested a girl in a public library.

The latest case against Nicholas C. Barghini, 31, alleges that the incident took place on April 22, 2017 at the Merriam Park Library. The girl was 9 at the time. Barghini was charged in Ramsey County District Court with one count of gross misdemeanor fifth-degree criminal sexual conduct.

The criminal complaint alleged a pattern of behavior similar to the three other cases against Barghini.

“Barghini instructed the girls to lie down on a couch with their shoes and socks off,” the complaint said. “He then positioned himself at the end of the couch, played with their feet, and masturbated.”

According to Wednesday’s complaint: authorities investigating the original cases searched Barghini’s home and recovered an external hard drive that contained videos of the April incident.

The videos, recorded with at least two video recorders and Barghini’s cellphone, showed him instructing the girl to read a scene from a phone three different times as she lay on her stomach across several wooden chairs.

Barghini allegedly knelt by the girl and touched her feet the first time. The second time, he sat next to her, placed her feet in his lap, tickled them and exposed his penis, which was not visible to the girl. He allegedly knelt by the girl’s feet, smelled them and masturbated.

The third time, he allegedly sniffed and “manipulated” her feet as he finished masturbating behind her.

Barghini was initially charged last summer with two counts of fifth-degree criminal sexual conduct in two separate cases at St. Paul’s Riverview Library last June and July. The girls were 8 and 10.

He was charged a third time last November with one count of felony second-degree criminal sexual conduct for a July 15 incident at the Merriam Park Library with a girl who was either 10 or 11 at the time. In that case, he allegedly touched and rubbed his genitals on the bottom of the girl’s foot and toes, according to court documents.

Barghini’s LinkedIn profile as posted last year said he is the owner of Headcase Films & Fashion. His online resume said he has volunteered as a youth camp counselor and sports coach.
