According to Nour News, the Romanian Police has also submitted a 29-page report to Iranian authorities.
The body of the 52-year-old judge was found at Bucharest's Duke hotel on June 19.
Mansouri, who was accused of taking a 500,000-euro bribe, was a co-defendant in a major financial corruption trial currently underway in Iran that also involves former deputy head of the Judiciary Akbar Tabari, among others.
Iranian authorities had issued an alert for Mansouri’s arrest through the International Criminal Police Organization and requested his extradition to Iran.
The ex-judge was arrested in Romania, but later released from custody and put under police watch.
He was found dead in the lobby of the hotel on June 19. On June 23, Romania said autopsy findings indicated that the he had died of the impact from a fall.
Bucharest’s prosecuting unit said in a statement that based on preliminary conclusions from the forensic autopsy, Mansouri's death was “caused by traumatic injuries incompatible with life, produced by hitting a hard surface."
