A bizarre internet conspiracy theory exploded into the real world on Sunday when a North Carolina man packed up his weapons, drove to a pizza parlor in Washington, D.C., and set out to “self-investigate” claims that Hillary Clinton and other top Democrats were hiding child sex slaves in secret tunnels there.

After firing his weapon inside Comet Ping Pong pizza and finding no evidence of an international pedophilia ring, Edgar Welch surrendered to authorities, the D.C. police said Monday. Nobody was hurt.
