A Jefferson County jury deliberated for just over an hour Tuesday before finding a high school band teacher, and the father of a small child, guilty of sexually assaulting a 16-year-old female student for a period of two months.
William Robert Eisenman, 33, a Bailey resident, was found guilty of one count of sexual assault of a child by one in a position of trust in a pattern of conduct, a class three felony. He was also found guilty of providing alcohol to a minor, a class four felony. The jury acquitted him of unlawful sexual contact involving another female student who had turned 18.
Eisenman was teaching band and orchestra at Evergreen High School in the winter and spring of 2007 when a female student approached him for advice about boys and relationships.
Eisenman had developed friendly relationships with many of the students and often acted as confidant, prosecutors said. Students considered him their friend as well as their teacher.
Prosecutors said when asked for advice about relationships, Eisenman suggested the female student dress and act more provocatively to attract boys. He also offered to let her model clothing for him and help her change her image at school.
In March 2007, he registered at a hotel room in the Denver area and drove the girl there so that she could model the clothing for him, the victim said.
That's where he sexually assaulted the teen for the first time, prosecutors said.
Over the next two months, he continued to sexually assault the teen at the school, in his car, in hotels, and at his home. During a jazz festival in Greeley, Eisenman invited a friend of his to the hotel room to have a "threesome" with the student.
Prosecutors showed the jurors how Eisenman had groomed the teen, by starting with being a good listener and friend.
But as their relationship grew, he told her that he had a heart condition that was incurable and that he would die within two to three years, prosecutors said. Eisenman told the girl that he was glad he could talk to her because he couldn't tell his wife about his heart because it would upset her. He also asked the teen to take care of his wife when he died.
Eisenman had worked for Jefferson Schools for about a year and had previously worked for a variety schools on the Western Slope.
After his verdict was delivered, Eisenman was remanded into the custody of the sheriff's office and his bond raised from $35,000 to $100,000.
He will be sentenced on Aug. 19.
He faces a mandatory prison sentence, ranging from eight years to life.
If Eisenman were to be paroled, he would be on lifetime parole supervision.
