Joshua Mastin

A Union man is facing sexual assault charges after police said he tried to entice a 12-year-old child.

Joshua J. Mastin, 36, was charged Wednesday, Nov. 28, in Franklin County Associate Circuit Court with one count of attempted statutory rape of a person less than 14 years old and one count of enticement of a child.

Union police said it received information regarding the possible enticement of a child on Sunday, Nov. 25. Police said a private organization, using an anonymous phone application, presented themselves as a 12 year old child.

The group made contact with Mastin and the conversation was sexual in nature.

According to the probable cause statement filed by the Union police department with the Franklin County Prosecuting Attorney’s Office, Mastin sent the child a sexually explicit picture. He also requested nude pictures from the child.

Police said Mastin described a number of sexual acts he wanted to perform on the child and requested a meeting.

Mastin then traveled to a motel in St. Louis County to meet up with the child. Union police said Mastin was confronted at the scheduled meeting and the encounter was video recorded by the private organization. The video was then posted on a social media page.

Police have seized the video of Mastin attempting to meet the child, according to the probable cause statement.

After identifying the man in the video as Mastin, police said Mastin admitted to communicating with the child about sexually related content, according to the probable cause statement. He also admitted to traveling to St. Louis to meet with the child.

Mastin gave police consent to search his phone and messages. Police said messages corroborating the incident were seized.

Police said Mastin admitted he is “attracted to juvenile females and having other similar conversations,” according to the probable cause statement. 

The charges came with a $50,000 cash only bond.
