HOUSTON, Texas (KTRK) -- The man shot to death by a U.S. Immigration and Customs Enforcement agent was one step away from obtaining his work permit, according to his sons.

Lorenzo Salgado Araujo was shot and killed Tuesday morning during what ICE claims was an attempted traffic stop as part of a targeted enforcement operation.

ICE alleges Salgado Araujo attempted to evade arrest, rammed his car into an ICE vehicle, and refused commands to stop.
