According to the East Bay Times, an argument about “sports and politics” led to a fatal stabbing in Oakley, California this Saturday.

Police arrested 38-year-old Phillip Wade for allegedly stabbing 57-year-old Anthony Johnson multiple times after they argued on a bus. Johnson later died at a hospital from his injuries. The altercation was stopped when a person passing by pulled out a gun and told Wade to get on the ground until police arrived.

Wade has a history of stabbing people. The East Bay Times reports:

In March of 2011, Wade stabbed 23-year-old Justin Garza in the Brentwood BART park-and-ride after an argument on the train carried into the parking lot. Garza survived the incident. Then in August of 2013, Wade fatally stabbed 49-year-old Kann Cendejas, a homeless veteran, at a Chevron gas station in the 3200 block of Delta Fair Boulevard in Antioch. … Wade’s Facebook page outlines increasingly hostile statements and threats towards Muslims and African-Americans. On May 19, Wade posted a threatening racist statement concerning former president Barack Obama along with the gun emoji and the emoji of a man wearing a turban. Desta said that Wade could be prejudiced at times, but described him as “more of a follower,” who became a “major Trump supporter.”

The victim of Saturday’s attack, Anthony Johnson, was black.
