A federal grand jury in Tucson has indicted Allman Rivas, 36, of Menagers Dam on the Tohono O’odham Nation, on four counts including Attempted Coercion and Enticement, Transfer of Obscene Material to Minors, Attempted Sex Trafficking of a Minor by Force, Fraud, or Coercion, and Sexual Extortion.
According to court documents, between June 26 and July 19, 2025, Rivas allegedly sent multiple Facebook messages to a minor in an effort to entice her to visit his residence for sexual purposes. He is also accused of sending photographs of his genitals to the minor. The indictment states that Rivas offered to repay a small loan if the victim engaged in oral sex and later threatened the victim when she refused his advances.
Rivas is an enrolled member of the Tohono O’odham Indian Nation.
If convicted on all charges, Rivas faces significant prison time: Attempted Coercion and Enticement carries a mandatory minimum sentence of 10 years up to life imprisonment; Transfer of Obscene Material to Minors has a maximum penalty of 10 years; Attempted Sex Trafficking of a Minor by Force, Fraud, or Coercion carries a mandatory minimum sentence of 15 years up to life; Sexual Extortion carries between five and fifteen years. Each conviction could also result in fines up to $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 investigation was conducted by the Tohono O’odham Police Department along with the FBI Phoenix Division’s Tucson office. Assistant United States Attorneys Nathaniel J. Walters and Alessandra C. Bermudez are prosecuting the case.
Authorities remind that an indictment is only an accusation; defendants are presumed innocent unless proven guilty in court.
