A convicted murderer has been arrested after sending unhinged, violent threats to outgoing Acting ICE Director Todd Lyons, including explicit calls for ICE agents to be “executed right there… with two f-cking bullets to the back of their maggot Nazi heads.” Daniel Barber, who has a lengthy criminal record that includes a 1990 conviction for murder and robbery with intent to cause bodily harm, was arrested on April 10 by Homeland Security Investigations (HSI) agents in San Francisco.
