A 23-year-old man is accused of stalking a 13-year-old girl online and threatening to kidnap her to force her to send him sexually explicit pictures of herself.

Craig L. Wyatt of Willingboro, befriended the girl, who told him she was 15, according to acting Attorney General John J. Hoffman.  After a series of "flattering" and "affectionate" texts between the two, she sent Wyatt a nude picture of herself, Hoffman said.

Hoffman said his messages via text and Facebook became more threatening — on 10 occasions telling the girl that if she didn't send more explicit photos, he'd kidnap her or post the pictures she'd already sent online.

"He allegedly said others were going to help him kidnap her and he was going to take her away and impregnate her," Hoffman said in an announcement from his office.

A family member became aware of the threats and contacted State Police, who arrested Wyatt on Oct. 31, Hoffman said. Detectives took Wyatt’s cell phone, allegedly discovering 36 sexually explicit images of the victim, 34 saved in his cell phone and two saved in his Facebook account, Hoffman said.

Wyatt faces 10 counts of first-degree manufacturing child pornography, three counts of second-degree theft by extortion, three counts of third-degree criminal coercion, third-degree possession of child pornography, third-degree making terroristic threats and fourth-degree cyber harassment.

The charge of first-degree manufacturing child pornography carries a sentence of 10 to 20 years in state prison, 85 percent of which must be served without parole.

Wyatt was previously charged with five counts of terroristic threats in Burlington and Atlantic counties for stalking other girls on Facebook and sending them threatening messages. He served 404 days in jail and was on probation at the time of the conduct alleged in the new indictment.

“In case after case, we see this alarming pattern of a predator who befriends a young girl using the anonymity of the Internet and then quickly turns from a friend into a terrifying stalker,” Hoffman said. “We urge parents to warn their children of these sexual predators, who ruthlessly exploit the fears of their young victims to gain control of them. We intend to make sure that Wyatt pays for the abhorrent crimes he allegedly committed against this child.”
