The suspected pro-Palestinian gunman who shot dead a young Jewish diplomatic couple in Washington DC has been unmasked as 30-year-old Elias Rodriguez.

Rodriguez, from Chicago, is understood to be a far-left activist who worked as an 'oral history researcher' on African American communities at educational non-profit TheHistoryMakers.

In the alleged shooter's profile, which has been deleted from the organization's website, it says his role was to 'prepare detailed research outlines and biographies of accomplished leaders in the African American community.'

He previously worked as a content writer in the 'technology space', the profile reads, and he holds a B.A in English from the University of Illinois at Chicago.

Images circulating on social media appear to show Rodriguez at a Black Lives Matter protest in 2017 on the three year anniversary of the police shooting of Laquan McDonald in Chicago, and he is believed to have been affiliated with the Part for Socialism group.
