Illegal Alien Arrested in Seattle Murder:  An illegal alien from El Salvador has been arrested for the brutal machete murder of a 16-year-old high school student.  Michael Spears of KIRO 7 reports that the partially dismembered body of Juan Carlos Con Guzman was found in a river last month.  20-year-old Carlos Iraheta-Vega has been named as a suspect in the murder.  Iraheta-Vega entered the country as an unaccompanied minor protected from deportation under the Obama Administration's DACA program.  According to federal Immigration and Customs Enforcement (ICE) officials, Iraheta-Vega was arrested three times, including twice for drunk driving.  On each occasion ICE asked King County police to hold him for deportation, but because King is a sanctuary county, he was released back into the community.  Local officials and an immigrant rights activist responded that the police would have violated the local sanctuary law if they had held Iraheta-Vega for ICE agents.  Now a teen-aged boy is dead.
