The purported mastermind of the schemes, the Malaysian financier Jho Low, faces charges in Malaysia and the United States, but he remains at large and is believed to be in China. His representatives have said that he denies wrongdoing and they call the case against him politically motivated.
Prosecutors have outlined a staggering list of things the money was spent on: a $250 million yacht named Equanimity; works of art by Monet and van Gogh; properties in California, London and New York; jewelry, including a 22-carat pink necklace worth $27.3 million; the production of Hollywood films and a see-through piano Mr. Low gave to the Australian supermodel Miranda Kerr.
(Ms. Kerr has surrendered jewelry given by Mr. Low and has offered to give up the piano, but it was walled into her Malibu, Calif., home, complicating removal.)
The Malaysian government announced Wednesday that it sold the yacht, which was seized in Indonesia last year, for $126 million to Genting Malaysia, a casino and resort company.
Last year, the Malaysian authorities said they seized jewelry, purses and other valuables worth at least $273 million and cash worth $30 million from properties owned by Mr. Najib and Ms. Rosmah. Counting the cash alone required 22 officials using six bill counting machines over three days.
Malaysia has also filed criminal charges against Goldman Sachs, accusing the Wall Street bank of making false and misleading statements and defrauding investors by raising more than $6 billion for 1MDB. The bank apologized for the role of a former partner who pleaded guilty to charges in the United States and it has sought to distance itself from the scandal.
The 1MDB case, as well as concerns about debt to China that piled up at a staggering rate under Mr. Najib’s rule, has been a rallying point for the administration of Mahathir Mohamad, the 93-year-old former mentor and ally of Mr. Najib who returned to the prime minister’s post last year vowing to clean up the mess.
