A federal grand jury in Tucson has indicted Allman Rivas, 36, of Menagers Dam on the Tohono O’odham Nation, on four counts involving alleged criminal conduct with a minor. The charges include 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 several Facebook messages to a minor victim in an attempt to lure her to his home for sexual encounters. He is accused of sending explicit photographs and offering financial compensation in exchange for sexual acts. When the victim refused his advances, Rivas allegedly threatened her in an effort to coerce compliance. Rivas is identified as an enrolled member of the Tohono O’odham Indian Nation.
If convicted of Attempted Coercion and Enticement, Rivas faces a mandatory minimum sentence of 10 years in prison with a maximum possible sentence of life. The charge of Transfer of Obscene Material to Minors carries up to 10 years in prison. Attempted Sex Trafficking of a Minor by Force, Fraud, or Coercion carries a mandatory minimum sentence of 15 years with a maximum of life. Sexual Extortion convictions can result in five to fifteen years imprisonment. Each count also allows for 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 case was investigated by the Tohono O’odham Police Department and the FBI Phoenix Division’s Tucson office. Prosecution is being handled by Assistant United States Attorneys Nathaniel J. Walters and Alessandra C. Bermudez from the District of Arizona’s Tucson office.
Authorities note that an indictment is not evidence of guilt; all defendants are presumed innocent unless proven guilty beyond a reasonable doubt in court.
