A Canadian man faces sentencing for his admitted role in an international pedophile ring he ran out of Thailand.

John Wrenshall (REN'-shall) could face up to 50 years in prison when he is sentenced Monday in a Newark, N.J., federal court.

Wrenshall pleaded guilty to three counts including conspiring to engage in sex tourism and to producing and distributing child pornography.

The 63-year-old detailed graphic abuse of boys as young as 4 years old.

Assistant U.S. Attorney Lee Vartan says authorities discovered Wrenshall was running a brothel for pedophiles in Thailand after confiscating computers from Union City resident Wayne Corliss.

Corliss is serving a 20-year sentence after admitting he traveled to Thailand to have sex with at least two boys.
