The case of a Dutch model who plunged to her death after partying with two American swingers at their 20th-floor Malaysian pad has been reopened as a murder investigation, according to new reports.

Authorities announced the new probe Wednesday into 18-year-old Ivana Smit’s death in Kuala Lumpur after a court determined that foul play may have been involved, the New Zealand Herald reported.

Smit was found dead in December 2017 on the sixth floor of an apartment building after she went home with Bitcoin millionaire, Alexander Amado Johnson, and his wife, Luna.

The couple admitted that they had a threesome with the teen model, but insisted that they were asleep when she fatally fell from their high-rise apartment.

“Ivana was our friend and we both had relationships with her,” Luna told the Daily Mail. “She came with us willingly that night.”

It was initially ruled that Smith’s fall was an accident, but her family successfully appealed the courts last week to reinvestigate the cause of death, Australian outlet 7News reported.

“The court ordered the attorney general to instruct the police to reinvestigate the cause of death, and for the case to be reclassified,” Bukit Aman Police Criminal Investigation Department chief Huzir Mohamed said.
