A math professor at Nassau Community College was acquitted of sex abuse charges Monday, nearly three years after a student first accused him of molesting her during a visit to his office.

It took a Nassau jury about two hours to find Alfred Magrella not guilty of forcible touching and sex abuse charges, lawyers in the case confirmed. Magrella, 59, of Dix Hills, was initially suspended with pay from his teaching position, but has since retired, his lawyer, John LoTurco, of Huntington, said.

"He feels that the justice system worked in his favor in the end, but he wishes there had not been so many delays," said LoTurco, adding that the 34-year teaching veteran can now enjoy his retirement in peace.

A spokesman for the Nassau district attorney's office declined to comment on the acquittal.

LoTurco said Magrella was first charged with molesting a female student in April 2010, when she went to his office for a makeup test. He said about a year ago, the woman changed her story, saying Magrella had raped her.

The district attorney chose not to bring rape charges against Magrella.
