Asadi, originally from Razan in Iran's Western Hamedan Province, worked at the Supreme Court in Tehran providing refreshments to judges and staff, said the source who spoke on condition of anonymity due to the sensitivity of the matter.
The assailant was initially assigned to the court’s fifth floor but was later relocated to the first floor after Judge Mohammad Moghiseh moved his office there.
On January 18, veteran judges Moghiseh and Ali Razini were shot and killed inside the Supreme Court building in central Tehran. The incident shocked the judiciary and remains largely unexplained by authorities.
The two clerics were central figures in Iran's theocratic establishment who had handed down death sentences and other harsh punishments on dissidents for decades. Supreme Leader Ali Khamenei led their funerals.
Their deaths marked a rare attack on senior officials as discontent over political repression and economic malaise festers in Iran.
The source told Iran International that Asadi first entered the room of a security guard and injured him before proceeding to the judges’ office. There, he shot Razini once, killing him instantly. As Moghiseh attempted to flee, Asadi fired again, striking him in the hand and then fatally in the back, piercing his heart.
Asadi, the source added, also intended to target another senior judicial figure, Mahmoud Toliyat, a former Revolutionary Court judge, but changed his mind for unknown reasons. He then turned the weapon on himself and died at the scene.
The full name, age and intended third target of the attacker was not previously reported.
Initial reporting by state-affiliated media suggested the attacker may have been an outsider or “armed infiltrator.” However, conflicting accounts followed, with judiciary-linked outlets later confirming the assailant was employed inside the court complex.
Following the shooting, several of Asadi’s relatives—including his father, uncle, maternal uncle, and two female cousins—were detained at different times by Iran’s Ministry of Intelligence, the source told Iran International.
It remains unclear how many are still in custody.
Separately, former political prisoner Bijan Kazemi has been held incommunicado for over 100 days in connection with the case. Authorities are reportedly attempting to extract a confession linking Kazemi to the firearm used in the attack. Asadi’s father is under pressure to admit involvement, the source added.
Judges Razini and Moghiseh, both clerics, were widely known for their roles in high-profile security cases and for issuing harsh sentences against political dissidents.
They were also involved in the mass execution of political prisoners in 1988, a chapter heavily criticized by human rights organizations.
