The death of former Enron Vice Chairman Clifford Baxter has been ruled a suicide by a Texas coroner.
Mr Baxter, who before his resignation last year complained about questionable financial deals that led to the company's bankruptcy and was sought by congressional investigators, was found in his Mercedes Benz with a .38-caliber revolver and a suicide note at his side early on Friday in the Houston suburb of Sugar Land.
Medical examiner Joye Carter conducted an autopsy on Mr Baxter's body on Friday and found the cause of death was suicide by penetrating gunshot to the head, a spokeswoman said.
Mr Baxter (43) resigned from Enron in May, just seven months after his promotion to vice chairman, for what the company said was a desire to spend more time with his family.
But a memo from Enron whistle-blower Sheron Watkins on August 14th to Chairman and Chief Executive Ken Lay indicated Mr Baxter had feuded with then-Chief Executive Mr Jeffrey Skilling about off-balance sheet deals the company was using to hide billions of dollars in debt.
Disclosure of those deals last autumn shattered the company's credibility and sank its credit ratings, which forced it into Chapter 11 bankruptcy in December.
The contents of Mr Baxter's suicide note have not been released, but it supposedly contained references to Enron. One news report said it indicated that Mr Baxter could not take the pain of his former company's collapse.
His death came a day after the start of congressional hearings in Washington on Enron's fall and the role of its auditor, Big Five accounting firm Andersen.
Congressional investigators sought to interview Mr Baxter last week while they were in Houston looking into Enron.
Mr Baxter was also a defendant in lawsuits targeting Enron's top executives, accusing them of cashing in on insider information.
Court records and securities filings show he sold more than half a million Enron shares for $35 million between October 1998 and early 2001.
