Former Enron Corp. Chairman Kenneth Lay and former Chief Executive Officer Jeffrey Skilling spent many years getting their way in the business world, but in the courtroom, where it really counted, the men and their skilled defense lawyers could not sway a jury hearing criminal charges against them.

On Thursday, a federal court jury in Houston found Lay guilty of all six criminal charges against him and found Skilling guilty of 19 of 28 charges against him. The jury found Skilling not guilty of nine insider-trading charges.
