Suspect in British MP Jo Cox Slaying a Longtime Neo-Nazi Supporter, Watchdog Group Says

The suspect has allegedly supported the U.S.-based National Alliance.

Cox, a British Member of Parliament (MP) and mother of two, was killed in a shooting and stabbing midday Thursday after a town hall meeting in West Yorkshire, England.

According to records obtained by the Southern Poverty Law Center, the U.S.-based organization that monitors hate groups, the suspect, whom the center identified as Thomas Mair, was a “dedicated supporter” of the National Alliance, a once-prominent white supremacist organization in the United States.

He purchased a manual from the National Alliance that included instructions on how to build a pistol, the center said.

Mair was charged with murder and weapons possession, West Yorkshire police said Friday night. They were not looking for anyone else and Mair's motives remain unknown.

Police search teams arrived this morning at the scene in the town of Birstall, where the investigation continues.
