Dante Beamon, 27, had agreed to the prison term when he pleaded guilty in May to first-degree attempted rape and second-degree burglary for the Nov. 15 campus attack. The maximum punishment for each charge is 15 years in prison.
However, Beamon must serve 15 years of sex offender supervision once he is released from prison.
Beamon, who was not a student at the college, entered the victim’s room on the Purchase campus around 1:30 a.m. Nov. 13. Prosecutors said he announced that the two were going to have sex and demanded that she remove her clothing.
After she ordered him to leave, Beamon tried to force himself onto her and choked her with an article of clothing, prosecutors said. The woman escaped and Beamon fled.
He was caught by university police a short time later and has been in jail since his arrest.
Beamon, 27, has a criminal history that includes charges of petty larceny, driving while intoxicated and resisting arrest, and has previously spent time in county jail, officials said.
The sexual assault was at least the fourth report of its type related to Purchase College last year. In one case in March, a student told police she was dragged into the woods by five men one night during spring break and raped by one of them. Several weeks later, two female students reported that a male stranger tried to enter a dorm and grabbed their buttocks. A third assault was reported a week later during an annual music festival in April. Authorities later classified that as a rape.
No arrests have been made in any of those cases, and police have said they don’t believe they are related. In both rape cases, police said, the alleged victims stopped cooperating.
SUNY Purchase drew scrutiny last year when officials did not alert students after the first two reported sexual offenses, later saying they did not want to “unduly alarm people.” The college did release an alert immediately after the music festival attack and after Beamon’s attack. It also has sent reminders to students about safety precautions and expanded the campus Blue Light security phone system.
