TEHRAN - The Iranian Legal Medicine Organization confirmed on Friday that the death of 22-year-old woman Mahsa Amini was not a result of alleged blows to her head or vital organs, semi-official Tasnim News Agency reported.

In its final statement on Amini's death, the forensic organization said the conclusion was drawn after examining the CT scans of Amini's brain and lung as well as her corpse, and according to the results of her autopsy and pathological tests.

Amini died because of ineffective cardiopulmonary resuscitation in the early minutes, which caused severe brain hypoxia, it noted, adding she was pronounced dead on Sept 16 at Tehran's Kasra Hospital after multiple organ failure despite all efforts to save her.
