CHERRY HILL, N.J. (CBS) — 25 years later, the investigation into the terrorist bombing of Pan Am flight 103 over Lockerbie, Scotland continues. One of the 270 people killed was a Syracuse University student from Cherry Hill, New Jersey.

Eileen Monetti’s son Rick was studying abroad and flying home when the bomb exploded. The only person convicted so far for the December 21, 1988 attack was Libyan Abdelbaset al-Megrahi. A probe to find others continues.

“The Scots and the Libyans announced this week that the Libyans are appointing special prosecutors to again look into the bombing,” Monetti says, “and to find out besides Megrahi who else is involved.”

She says it’s been 25 years and there are still a lot of unanswered questions.

“We are hoping that we will finally get some answers to them in the not so distant future,” Monetti says. “I look at the bombing of Pan Am 103 as kind of being a precursor to what we see as a terrorist acts that have unfortunately happened to our country over and over again. And we really didn’t learn from Pan Am 103. Some of the things we could have learned might have helped avoid some of the other problems that we had.”

The Monetti family attended a service on Saturday at Pan Am Flight 103 Memorial Cairn at Arlington National Cemetery.

Memorial services were also held in a number of other places for victims of Pan Am flight 103, including in Lockerbie, in London and at Syracuse University.
