WOODBURY - The death today of Moammar Gadhafi marks the end of a long road to justice for a Long Island family who lost its son in the bombing of Pan Am Flight 103.

Gadhafi was the mastermind behind the 1988 bombing over Lockerbie, Scotland, and while his death brings a sense of relief, the family says it's bittersweet.

Peter Lowenstein has spent the past 23 years waiting and hoping for justice for the man he knew was ultimately responsible for killing his 21-year-old son Alexander Lowenstein. He was on his way home for Christmas break from a semester abroad.

The bombing claimed the lives of 270 people. Libyan rebels storm seat of Gadhafi's power
