Three Men In Custody After ICE Agent's Death

Arrests have been made in the shooting death of U.S. immigration agent.

Yesterday federal agents arrested a Dallas-area man who they say is linked to the gun used to kill the ICE agent.  Two other suspected gun smugglers were handcuffed during those raids.  Then earlier this week, Mexican authorities arrested the regional head of the Zetas drug gang, all in connection to last weeks shooting.
