A 24-year-old man accused of killing his wife just weeks after their wedding has been taken into custody in Texas and US immigration officials have urged that he not be released.Francisco Mendez-Marin is an undocumented immigrant from Mexico and was arrested by the Carrollton Police Department on March 18 and charged with felony murder. He is accused of slitting the throat of his 20-year-old wife, Carla Rangel, during a domestic dispute in Dallas.According to officials, the couple had been married for less than a month at the time of the incident. When police arrived at the scene, Mendez-Marin had blood on his clothes and a bloodied pocket knife.Body camera footage cited in the arrest affidavit shows him telling officers in Spanish, “I didn’t do anything bad” and “I was obligated to do this.”Following the arrest, the Department of Homeland Security (DHS) said it filed a detainer case with Immigration and Customs Enforcement (ICE), requesting local authorities not to release the suspect from custody. Mendez-Marin is currently being held at the Dallas County Jail in the custody of the Dallas County Sheriff’s Office.Acting Assistant Secretary of DHS Lauren Biss released a statement on the matter. He said, “This evil animal murdered his own wife by brutally slitting her throat with a pocket knife just a month after their marriage.” “This illegal alien should never have been allowed into our country to commit this heinous murder.”He added: “ICE urged authorities in Dallas not to release this ruthless killer on the streets. Thankfully, Dallas politicians cooperate with ICE, so together we can ensure this killer never runs free in American communities.”
