Probe May Shed Light on Maxwell Mysteries : Scandal: Investigators expect to find some answers to the media empire’s missing millions, as well as the mogul’s cause of death.

The Maxwell mysteries--how Robert Maxwell died and what happened to his media empire’s missing millions--are still going strong and making headlines, but investigators expect to edge closer to the truth this week.

Liquidators winding up Maxwell businesses are pressing the tycoon’s son, Kevin, to clear up another mystery surrounding more than $500 million (about 300 million pounds) in assets missing from pension funds at Maxwell companies.

Kevin, who has been banned from travel and had his personal assets frozen until the matter is resolved, must submit a sworn statement about the funds to the High Court today.

Kevin, 32, pledged through his lawyers Friday to “spend every waking hour” tracing the pension assets.

But in a clear sign the lawyers believe that criminal charges may arise, attorney George Carman said he had advised Kevin of his right to silence “in advance of any prospective criminal charge” when dealing with liquidators.

Kevin is due to be questioned Tuesday by a parliamentary committee probing the Maxwell affair. The next day he meets with provisional liquidators Rhodes Robson.

Maxwell’s own Sunday Mirror newspaper added to the speculation over his bizarre death at sea last month with a banner headline proclaiming “SUICIDE.”

Flying in the face of assertions by the Maxwell family that the publisher would never have fled creditors by taking his own life, the Mirror quoted unidentified sources close to pathologists acting for Maxwell insurers as saying they were “90%” sure that he killed himself.

If the death is ruled a suicide, the insurers may refuse to pay out $36 million (20 million pounds) in accident insurance coverage held by companies in Maxwell’s shattered empire.

A report by British pathologist Ian West, which could be released within the week, is likely to shed important light on the exact cause of Maxwell’s death but could also spark a court battle over the insurance payout.

The Maxwell business giant has been toppled by mountainous debts a month after the 68-year-old tycoon died off the Canary Islands during a cruise aboard his luxury yacht.

A Spanish autopsy report indicating that he had a heart attack has failed to silence questions about the death.

The Sunday Mirror said investigators found Maxwell’s heart was healthy and had concluded that he jumped overboard to avoid the scandal about to engulf his byzantine business empire.

Britain’s Serious Fraud Office is investigating the transfer of pension money before and after Maxwell’s death, as well as allegations that he used some of his plunder to buoy shares in his flagship company, Maxwell Communication Corp.

Accountants Price Waterhouse are to publish a preliminary report on the company on Wednesday.
