Fugitive 1MDB-linked businessperson Jho Low might be killed off as he "knows everything", former PetroSaudi executive and whistleblower Xavier Justo (above) has stated.

"He is the one who knows every­thing from PetroSaudi to Goldman­Sachs, IPIC, 1MDB scams.

“For a lot of people, the best solution would be for him to disappear forever.

“I would not be surprised if Jho Low is not seen anymore or is found dead," Justo said in an interview with The Star.

He added that he, however, did not wish for this to happen and that Low should be brought to court.

Low, whose real name is Low Taek Jho, is believed to be the mastermind behind the 1MDB scandal and is currently sought by several countries, including Malaysia, to facilitate its probe into the beleaguered fund.

The US Department of Justice had claimed that the Penang-born businessperson was central to the misappropriation of more than US$4 billion of 1MDB funds.

His whereabouts are currently unknown, but there is speculation that he might be in China.

Recently, former defence minister Hishammuddin Hussein offered to track down Low in China as he wants to see closure to the 1MDB case.

Justo said Low would likely still be living in luxury.

"These people (Low and his kind) are big spenders. In a hotel, they would take an expensive suite.

“He would not hide forever in a small Cambodian fishing village. I am sure that even now he is living a high life, spending large amounts of money for bottles of wine and nice parties,” Justo was quoted saying.
