ALBANY — “You have committed one of the worst crimes against another person,” the older sister of Franklin Casatelli’s rape victim told him in Albany County Court on Monday, just before he was sentenced by Judge Thomas Breslin to 37 years in state prison.

But his crime will not define her sister, the young woman continued in a victim impact statement, speaking on behalf of the victim and her entire family.

A jury had found Casatelli guilty, in December 2017, of entering an unlocked dormitory room at the University at Albany in October 2016 and, there, raping a student as she slept. The crime was committed just 10 days after Casatelli was released from prison on drug changes.

Only Casatelli’s life, the sister continued, will be defined by the rape. He will “forever be defined as a sexual predator, a rapist,” she said as Casatelli stood listening, expressionless.

“You will spend,” she told Casatelli, “the best years of your life sitting in a cell, while a world of opportunity passes you by.”

And, even after the “unfortunate and regretful day” when he is released, his act will determine where he can live, where he will work, and “every association you have, for the rest of your life,” she said.

The permanence of its effect on him, she said, gives her some peace.

Breslin sentenced Casatelli to 22 years for first-degree rape, and 15 years for second-degree burglary as a sexually motivated felony, both felonies. These sentences were to be, Breslin said, served consecutively. Both of these crimes means he will be listed on the sex-offender registry.

An additional charge, third-degree criminal trespass, brought a one-year sentence, to be served concurrently.

Breslin said that Casatelli would serve 25 years of post-supervision release on the rape charge, and 10 on the burglary. Spokeswoman Cecilia Walsh of the Albany County District Attorney’s Office told The Enterprise that post-supervision release “maxes out at 25 years.”

Casatelli’s attorney, James Tyner, told the judge that he intends to appeal.

The charge of burglary is for entering the dorm room, Walsh said. In New York, the crime of burglary is defined as illegally entering premises with the intent of committing a felony within.

The criminal trespass charge is for Casatelli’s efforts to enter a different room in a nearby dorm, before the rape, by following a woman upstairs after she had gone downstairs to get a pizza from a delivery driver. Casatelli followed her upstairs to her room, asking her to hang out and saying, “I’m not trying to fuck you or anything,” the woman had testified at the trial. After her roommate opened the door for her and the two of them slammed it on Casatelli, he continued to knock and plead to be let in, the roommate also testified.

Before finding his way to the victim’s room sometime later that night, Casatelli spoke to numerous people he encountered on campus. The unifying feature of these encounters was that people — women and men alike — gave him, when asked for their names, fake names.

Several young men testified they had been outside, smoking, when Casatelli — a stranger to them — came up and started talking, telling them, among other things, that he had just had sex with a girl in the tower who was asleep. When Casatelli asked their names, they gave him made-up names, they testified.

If Casatelli’s account on the stand were to be believed, the only one who gave him a real name that night was the victim. He testified that he had met her a few hours earlier, at a house party off campus, and that she told him her name, the name of her hometown, the name of her dorm, and her room number, and asked him to drop by.

Before announcing his sentence, Breslin said of Casatelli’s testimony, “He gave a story about how he was so attractive the victim invited him uptown — a statement the jury obviously rejected out of hand.”

The campus has security cameras on the outside of the dormitory buildings, focused on the entrances, but does not have any interior cameras in the hallways, so there is no footage showing whether Casatelli wandered hallways, trying doorknobs before discovering an unlocked room housing female students.

The jury had seen police photographs of the suite door itself, which was decorated, like many other rooms in the hallway, with the first names of all of the residents inside.
