The suspect behind the shooting at the YouTube HQ was a 39-year-old transgender woman from San Diego, California named Nasim Aghdam. Nasim was "angry" with Youtube after it was de-monetised and removed from the video-sharing website.
Some reports are saying that she's Iranian - or Persian - because she speaks Farsi. But those reports are wrong. Nasim's parents are ethnically from Armenia and Azerbajian, even though they lived in Iran. Also Nasim grew up Jewish and lived as a male for half her life.
Nasim described herself on her website as a Persian animal rights activist and vegan athlete, opened fire with a handgun at YouTube HQ on Tuesday just before 1pm, Pacific Time.
