LONDON — Convicted Lockerbie bomber Abdelbasset al Megrahi returned to a hero’s welcome in Libya a year ago today.

He’d been sentenced to life in prison for his role in the 1988 terror act against Pan Am flight 103, which left 270 people dead, most of them Americans.

He was released by the Scottish government last year on what was called “compassionate grounds.” He has terminal cancer and it was claimed he had three months to live.

He’s still alive.

“This is a man who showed absolutely no compassion to anyone,” wife of a Lockerbie victim Stephanie Bernstein told Fox News, “What about compassion for people so cruelly murdered that night?”

Also “alive” are questions surrounding Megrahi’s release.  It’s been claimed it was engineered to pave the way for trade deals between the U.K. and Libya, including an exploration and drilling contract with energy giant BP, already in the investigators’ spotlight for its Gulf oil spill. BP denies it argued for Megrahi’s release.

And there are questions about the medical basis for Scotland’s decision. The doctor who made that three-month prognosis now says he’s not sure.

Members of the Senate Foreign Relations Committee, who have been raising these issues and more, say they’re not giving up.

“We want it to be known that our desire for answers is as strong as ever,” New Jersey Sen. Robert Menendez declared. “Our resolve is deep and our determination won’t fade.”

And President Obama’s counter-terrorism advisor expressed the administration’s displeasure:

“We have made it clear repeatedly,” John Brennan said, “that we disagree with the decision to release Megrahi.”

For their part, Scottish authorities stand by the move.

“It was without recourse or consideration of political, economic or diplomatic matters,” Scottish Justice Secretary Kenny MacAskill stated, “whether they affect the governments of Libya or America.”

In Libya, Megrahi and his associates are keeping a low profile.  The U.K. government had warned Tripoli a replay of last year’s celebrations would be “tasteless and offensive.”

As for Megrahi’s condition, Scottish government sources tell Sky News that he had been on chemotherapy, was now off it, and had “weeks maybe days” to live.  But that’s been said before and others claim he could live for months more or years.
