HOUSTON (AP) - Lawyers for Enron Corp. founder Kenneth Lay took their first official step Wednesday toward erasing his felony convictions in light of his death last month. Lay, 64, was convicted May 25 of fraud and conspiracy in the federal government's foremost criminal trial to emerge from the disgraced company's flameout. His co-defendant, former Enron CEO Jeffrey Skilling, 52, was convicted of 19 counts of fraud, conspiracy, insider trading and lying to auditors. .
