Authorities have identified the man known as “Mike King,” who worked security for high‑profile Dallas banks, hotels and U.S. Rep. Jasmine Crockett, as 39‑year‑old Diamon‑Mazairre Robinson, a convicted felon with multiple theft convictions who used an alias to pass himself off as law enforcement. Robinson was killed Wednesday night after pulling a gun during an hours‑long standoff in a Dallas hospital parking garage, raising new questions about how he was able to operate inside secure environments, including the U.S. Capitol.
