Don-Diego Parkman, 19, is being charged with aggravated sexual assault, manufacturing child sexual abuse material (CSAM), as well as endangering the welfare of a child, acting Mercer County Prosecutor Theresa L. Hilton announced on Tuesday.
The prosecutor's office said they have also filed a motion to detain Parkman pending trial.
The Mercer County Prosecutor's Internet Crimes Against Children (ICAC) Unit and the New Jersey State Police ICAC Task Force said they received information earlier this month from law enforcement in Missouri about a minor in their area who had been allegedly chatting and exchanging child sexual abuse material with Parkman.
Detectives claim Parkman was directing the preteen girl to take photos and videos of herself engaging in sexual conduct to send them to him.
Last week, the ICAC Unit, as well as the Hamilton Police SWAT Team, executed a search warrant at Parkman's home, where detectives said they seized multiple items of "evidentiary value."
Parkman was also taken into custody at that time.
According to the prosecutor's office, during the past year, Parkman has been working as a "costumed character and mascot" at several companies, including Somerset Baseball Partners, Devils Arena Entertainment, and most recently, Sesame Place in Langhorne, Pennsylvania.
"Parkman is no longer employed by Sesame Place. His arrest is not related to Sesame Place, and any questions should be directed to the Mercer County Prosecutor's Office," Sesame Place said in a statement.
A former female coworker said she wasn't surprised by the charges.
"I know that a lot of young girls and women, including myself, were uncomfortable with how he treated, looked at, and how he spoke to them," said the woman.
Devils Arena Entertainment says Parkman hasn't worked for them since April and he will not return this season.
The prosecutor also said Parkman worked at Six Flags Great Adventure. However, in a statement, Six Flags told Action News that Parkman was hired after passing a criminal background check, but "never completed the process and therefore never actually worked."
