Nassau County, New York (WSYR-TV/CNN) -- Investigators say a Hofstra University student who died during a confrontation between a home invasion suspect and authorities was killed by police gunfire.
Authorities say 21-year-old Andrea Rebello was shot once in the head by an officer who opened fire on the intruder. Investigators say that intruder was holding a gun to Rebello's head during a robbery Friday at an off-campus house in Uniondale.
The intruder, whom authorities identified as Dalton Smith, 30, of Hempstead was also killed after being hit seven times.
Authorities say on Friday Smith was wearing a mask when he invaded the home Rebello shared with her twin sister and two others.
At some point, a female roommate of the twins was able to leave the home and call police, a police spokesman told CNN on Friday.
When a police officer arrived, Smith was holding a gun to Rebello's head, police spokeswoman Maureen Roach said.
Investigators say Smith then told the officer he was going to kill Rebello, and then turned the handgun toward the officer.
The officer, fearing for his life, drew his gun and fired, Roach said.
Authorities have not identified the officer.
At the time of the shooting, Smith was wanted for jumping parole, police said.
He was on parole for first-degree robbery and had an "extensive" arrest history that includes robbery, assault, and promoting prison contraband, said police in Nassau County.
Rebello, a junior, was majoring in public relations.
Hofstra University said it is offering counseling to students.
"Our hearts and minds and our thoughts and prayers are with her family, her friends and her classmates," the university said in a statement.
A funeral mass is planned for Wednesday.
