In a matter-of-fact update that did not address the conspiracy theories swirling in right-wing media, Austin police said that Mr. White, 36, was trying to thwart his vehicle from being stolen outside his apartment complex on Sunday night when someone shot him and fled. Mr. White later died at the hospital.

Alex Jones, the founder of Infowars, said one of his reporters, Jamie White was killed in Austin. Police later confirmed his identity.

On his show Monday, Jones said the staff member, 36-year-old Jamie White, was “brutally murdered” outside his home, a few miles from the Infowars office. Austin police later confirmed White was shot and killed outside the Chandelier Apartments.
