San Jose: A man, whom prosecutors said was one of the most prolific child molesters in the United States, was sentenced on Monday to 152 years in prison for abusing two 12-year-old boys.

Dean Arthur Schwartzmiller, 64, who also had been convicted of sexual assaults in several states over three decades, was sentenced to the maximum term on 11 felony counts of child molestation and one misdemeanour charge of child pornography possession.

During the nearly three-week trial, prosecutor Steve Fein showed jurors a map of the "places and decades where the defendant has molested young boys". It included an estimated 100 accusers dating to 1969 in eight US states, Mexico and Brazil.

Schwartzmiller was arrested in June 2005 following which investigators found a memoir describing abuse, binders full of child pornography and 1,500 notebook pages with headings, including "blond boys", "no, but yes boys", and "best of the best, 13 and under".
