TRENTON — Authorities say a man accused of blackmailing five teenage girls to pose nude and engage in sexual conduct on web cameras has pleaded guilty to manufacturing child pornography.

State Attorney General Christopher Porrino says Daniel Derringer III also pleaded guilty Friday to distributing child pornography and debauching the morals of a child.

The 28-year-old man faces up to 12 years in prison when he's sentenced Feb. 9. He also will have to register as a sex offender.

Authorities say the former Union City resident posed online as a young girl to trick teen girls into exposing themselves on their web cameras. Investigators say he threatened to post those images online if the girls did not engage in further sexual conduct.

He was arrested after he moved to Florida. Porrino in March described Derringer as a “serial sexual predator."
