This legislation, titled "Sarah's Law," mandates that U.S. Immigration and Customs Enforcement (ICE) take custody of certain aliens who have been charged with, arrested for, or convicted of crimes that resulted in the death or serious bodily injury of another person. It amends Section 236(c) of the Immigration and Nationality Act to expand the categories of aliens subject to mandatory detention . Specifically, it targets aliens who are inadmissible or deportable and have committed such offenses, requiring ICE to issue a detainer and expeditiously take custody. The bill also imposes a significant notification requirement on the Secretary of Homeland Security. Upon encountering or learning about such an alien, the Secretary must gather information about the victims and provide timely, ongoing updates to the victim or their closest relatives. This information includes the alien's identity, immigration and criminal history, custody status, and details regarding any government efforts to remove the alien from the United States.
