Police probe substance use in Harry Yeh’s 30th-floor fall

On Aug. 7 investor Harry Yeh fell from the 30th floor of the Jade Park apartment tower in Asuncion. Paraguayan police are investigating whether drugs or medication played a role. An autopsy recorded multiple trauma consistent with a fall, but no blood could be extracted and toxicology tests could not be performed.

Yeh was the managing partner and founder of Quantum Fintech Group, an investment fund that managed more than $2 billion. His body was found on the ground outside the tower naked, with a black bag covering it. Pablo Lemir, director of Legal Medicine and Forensic Sciences at the Public Prosecutor’s Office, told investigators examiners found no gunshot wounds or injuries from a sharp object and that the injuries matched those expected from a fall.

Francisco Ávalos, director of police in Asuncion, told investigators a building worker reported seeing a foreign man walking naked through parts of the complex the day before the fall. “He saw him wandering through parts of the building completely naked,” the director added. Ávalos noted the sighting matched the state in which Yeh was found.

Ávalos said Yeh could have been mentally affected or under the influence of a substance or medication, but he did not rule out foul play. Police pointed out the area where the fall occurred is difficult to access without being seen because of the complex’s security measures. Investigators are reviewing surveillance footage and witness accounts to establish movements inside the building.

Officers reported Yeh’s apartment was found in disorder after the incident; investigators are treating that as one of several possible explanations. The inability to run toxicology limits what forensic examiners can determine about Yeh’s state before the fall.

Authorities continue to piece together the timeline and circumstances. While there has been an increase in attacks and robberies targeting wealthy cryptocurrency holders globally, police have not linked Yeh’s death to any targeted crime. Investigators say they will follow forensic leads, witness testimony and security records as they seek to clarify events.
