A Sacramento pilot who traveled overseas to sexually abuse underage girls and worked with a woman in the Philippines to produce child pornography was sentenced Tuesday to life in prison.

The sentencing of Michael Carey Clemans, 57, comes four months after a federal jury in Sacramento found him guilty of a variety of charges, including traveling overseas to engage in illicit sexual conduct and buying children. He pleaded guilty to separate counts of producing child pornography and receiving child pornography at the start of the trial.

Clemans worked with an overseas associates to locate vulnerable children, directing them to seek out orphans or the victims of typhoons, court documents say.

He is one of 40 people facing sentences ranging from 15 years to life in connection to crimes committed against children and prosecuted by the Eastern District of the California United State’s Attorney’s Office in the past four years, said McGregor Scott, the federal office’s top attorney. Of that group, 16 face sentences of 25 years or more.
