HICKSVILLE - Families who lost loved ones in the Sept. 11 attacks say it's been a day full of emotions as they relive the events that occurred nearly 10 years ago, in the wake of Osama bin Laden's death.

Many friends and family members say the news first brought a sense of happiness and relief, but that those feelings turned to sadness as they are forced to mourn their losses again.

Dierdre Kroupa lost her brother, former News 12 Long Island videographer Glen Pettit, on Sept. 11. She says hearing that bin Laden was killed in Pakistan brought back every single emotion she felt on that day.

At firehouses across Long Island, volunteers say they are taking the time to remember fellow firefighters that they lost at Ground Zero.
