A local man, Robert Adams III, pleaded guilty Tuesday to a charge of first-degree rape of a Syracuse University graduate student in July, according to WSYR channel 9’s 6 p.m. newscast.

Adams committed the rape the day after being released from the Collins Correctional Facility on July 25. He was serving a 33-month sentence on a burglary charge, as reported by The Daily Orange.

His guilty plea came with promise of a 20-year sentence in a state prison. Adams could have been sentenced to a 75-year penalty if he had been convicted of additional counts of first-degree criminal sexual act, along with the first-degree rape charge he already admitted to, according to The Post-Standard.

On the day of the crime, Adams was walking down Stratford Avenue when he grabbed the graduate student from behind and dragged her into a residential garage and committed the sexual assault, as first reported in The Daily Orange. The student was able to break free and run away. She then received treatment at a local hospital.

Adams was 21 years old at the time of the incident, and he was arrested by the Syracuse Police Department at the Syracuse Rescue Mission after the police linked him to the case through DNA evidence.
