Queensland pedophile Peter Truong, who bought a newborn boy for $US8000 and then allowed men around the world to be abuse the child, has been sentenced in a US court to 30 years’ jail.

Truong, 36, faced a maximum 40-year sentence, while the plea deal he struck with prosecutors could have allowed a minimum of 24 years.

US District Court judge Sarah Evans Barker, in announcing the sentence on Monday in Indianapolis, took note of Truong’s willingness to work with authorities to lead them to other pedophiles and his own history as a childhood abuse victim.

Truong’s domestic partner, Mark Newton, 42, also from Queensland, was jailed in June for 40 years.

Prosecutors say Truong and Newton bought the boy from a woman in a “foreign” country, believed to be Russia, and then transported him around the world to engage in sex with more than half a dozen other men, all before his sixth birthday.

Truong entered guilty pleas to one count of conspiracy to sexually exploit a child and conspiracy to possess child pornography.

Prosecutors asked that Truong be sentenced to 33 years’ imprisonment.

Truong and Newton were arrested in Los Angeles in 2011 and the boy was taken into protective custody.
