Tohono O’odham Man Indicted on Multiple Charges Involving Minor Victim

TUCSON, Ariz. - Last week, a federal grand jury in Tucson returned a 4-count indictment against Allman Rivas, 36, of Menagers Dam, located on the Tohono O'odham Nation, for Attempted Coercion and Enticement, Transfer of Obscene Material to Minors, and Attempted Sex Trafficking of a Minor by Force, Fraud, or Coercion, and Sexual Extortion.

Pursuant to the complaint and indictment filed in this case, between June 26, 2025, and July 19, 2025, Rivas sent multiple Facebook messages to a minor victim to entice her to go to his residence for sexual encounters. During this period, Rivas also sent the minor victim photographs of his genitals. At one point, Rivas offered to pay back a small loan to the minor victim if the minor victim engaged in oral sex. Finally, when the victim refused to engage in sexual acts with Rivas, Rivas threatened the minor victim to coerce them to engage in sexual contact or sexual intercourse. Rivas is an enrolled member of the Tohono O'odham Indian Nation.

A conviction for Attempted Coercion and Enticement carries a mandatory minimum penalty of 10 years in prison with a maximum term of life. A conviction for Transfer of Obscene Material to Minors carries a maximum term of 10 years in prison, and a conviction for Attempted Sex Trafficking of a Minor by Force, Fraud, or Coercion carries a mandatory minimum of 15 years in prison with a maximum term of life. Finally, a conviction for Sexual Extortion carries a term of imprisonment of between 5 and 15 years. Each conviction also carries a maximum fine of $250,000.

"Protecting our youth from sexual offenders is one of the highest priorities of this office," said United States Attorney Timothy Courchaine. "These crimes are among the most serious we prosecute because they target the most vulnerable members of our community. Working closely with our law enforcement partners, we will continue to aggressively investigate and prosecute those who attempt to exploit children."

"Safeguarding all children from violence, coercion and exploitation is a top priority for the FBI," said FBI Phoenix Special Agent in Charge Heith Janke. "The FBI will continue to work with our federal, state, local, tribal, and law enforcement partners to identify, prioritize and investigate anyone who seeks to harm the most vulnerable among us."

The Tohono O'odham Police Department and the FBI Phoenix Division's Tucson office conducted the investigation in this case. Assistant United States Attorneys Nathaniel J. Walters and Alessandra C. Bermudez, District of Arizona, Tucson, are handling the prosecution.

An indictment is a formal accusation of criminal conduct. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
