Saleh's decapitated and dismembered body was found in an apartment in a luxury $2.25 million condominium on Manhattan’s Lower East Side on Tuesday, July 14.

Saleh’s personal assistant, Tyrese Devon Haspil, 21, is expected to be charged in a criminal complaint with second degree murder and other crimes, the New York Times (NYT) reports. 

Detectives believe that Haspil’s motive for allegedly killing Saleh stems from the fact that the Gokada CEO discovered that the assistant had stolen tens of thousands of dollars from him.

Saleh did not report Haspil to the authorities but set up what amounted to a repayment plan for him to return the money, one of the officials briefed on the matter told NYT. 

The police are expected to announce the arrest at a news conference soon. 

Investigators have also concluded that Saleh was killed on Monday, July 13, the day before his body was found, and that the killer returned the next day to the apartment on East Houston Street to dismember the body and clean up the crime scene.

On Thursday, the police had said Saleh's murder stemmed from a business deal gone bad and that it was "financially motivated."

Saleh had died from multiple stab wounds to his neck and torso, according to New York City’s medical examiner.

A taser was first used to immobilize him.
