Phoenix Man Sentenced to 188 Months for Child Exploitation Offenses | USAO-AZ

TUCSON, Arizona – Robert Allen Yost, 61, of Phoenix, Arizona, was sentenced to 188 months in prison on child exploitation charges by U.S. District Judge Jennifer G. Zipps on October 21, 2022. Yost previously pleaded guilty to conspiracy to traffic in child sex and production of child pornography, and to conspiracy to transport illegal aliens for profit. Upon release from prison, Yost is placed on supervised release for life with sex offender conditions and must register as a sex offender.

In March 2020, U.S. Border Patrol agents first stumbled upon Yost smuggling undocumented non-citizens along State Route 80 when a search of his phone revealed content related to child exploitation. During his guilty plea on January 18, 2022, Yost admitted to exchanging images and videos depicting child sexual abuse with others via text messages and the internet. He also admitted that he asked another person to send sexually explicit images of a child in that person’s care and offered methamphetamine in exchange for having sexual access to the child. The intended sexual activity with the child did not materialize due to other intervening circumstances.

This case was brought as part of Project Safe Childhood, a nationwide initiative launched by the Justice Department in May 2006 to combat the growing epidemic of child sexual exploitation and abuse. Led by U.S. Attorneys’ offices and the Department of Justice’s Child Exploitation and Obscenity Division, Project Safe Childhood provides federal, state, and local resources to better identify, apprehend, and prosecute those who exploit children online as well as identifying and rescuing victims.
