A former Eugene elementary school teacher on Tuesday pleaded guilty to sex trafficking a 15-year-old girl.
Federal prosecutors will seek a prison sentence of 13 years and four months for William Cantu Hamann, 38, when he’s sentenced in U.S. District Court in Eugene on March 1.
They’ll ask that the sentence run consecutive to a proposed state prison term of one year and eight months, according to global plea negotiations from both federal and state cases.
Hamann is accused of sexual abuse and sodomy in Lane County Circuit Court and has not formally entered any pleas in the state case. A trial is set there for March 10.
The victim was not a student of Hamann, according to prosecutors. He had taught at Spring Creek Elementary in Eugene and operated the Frightuary haunted house at Lane Events Center in October 2018, according to Eugene police.
Hamann met the girl on social media, paid the girl for oral sex and recorded her performing sex acts between 2018 and July 2019, according to federal prosecutors. She was 15 at the time Hamann first met her.
Eugene police detectives and FBI agents arrested Hamann on July 26, 2019, when he arrived at a local school to meet the teen, according to Eugene police. He was accused of meeting the teen, then 16, for oral sex, on that day, according to his plea agreement. Agents searched his cell phone and found a recording of one of the sex acts, according to court documents.
As part of the federal plea agreement, Hamann has agreed to pay an undisclosed amount of restitution to his victim.
Eugene police said at the time of Hamann’s arrest that they had no indication that any children at the school where Hamann taught were victims.
