NEW YORK (CBSNewYork/AP) — The Nassau County police officer who fired the fatal shots that killed a Hofstra University student and the armed intruder who was holding her hostage will not face criminal charges.

Nassau County District Attorney Kathleen Rice issued a 28-page report Wednesday on the May 17, 2013 shooting, following a review of whether police personnel acted appropriately during the deadly confrontation.

DA: No Criminal Charges For Officer Who Killed Hofstra University Student

Rice said prosecution of officer Nikolas Budimlic, a 19-year police veteran, is not warranted, CBS 2’s Tracee Carrasco reported.

Budimlic was one of the first officers to respond to the break-in at an off-campus apartment in Uniondale. Police said the officer found an intruder — Dalton Smith, 30 — holding Andrea Rebello, 21, in a headlock and threatening to kill her.

The officer fired when Smith pointed a gun at him, police said.

Smith “kept saying, ‘I’m going to kill her,’ and then he pointed the gun at the police officer,” according to county homicide squad Lt. John Azzata. The officer acted quickly, saying later that he believed his and Rebello’s life were in danger, according to authorities.

Smith was hit seven times, Rebello once.

“Andrea Rebello’s death was not caused by any criminal misconduct by Officer Budimlic. Her death was caused by Dalton Smith’s decisions,” the report read. “Officer Budimlic reasonably perceived threats of deadly force against himself and others and acted accordingly. Though the results were unquestionably tragic, criminal charges under these circumstances would be inappropriate and legally unsustainable.”

As CBS 2’s Jennifer McLogan reported Wednesday, some students reacted with passion to the incident – with some arguing that Budlimic should be held responsible for Rebello’s death.

“Police are trained to use guns and weapons. That’s part of the job,” said Aaron Rodwin, a former classmate of Rebello’s. “When they have situations like this where they might have to shoot, they need to know when is the right time to do it, and they need to also be accountable for their actions.”

“That’s what he thought he should have done, but that was not the best call,” said former Hofstra student Jared Goodman. ”Obviously, she’s dead, and the whole Hofstra community was mourning afterwards.”

“I believe he was in a very tricky situation,” added student Danielle Gresalfi, “At that point he was trying to think what would be best for her interests.”
