From 2010 to 2014, 121 undocumented immigrants who committed crimes but were released while awaiting deportation were later charged with homicide, according to the Department of Homeland Security.

The disclosure came in response to questions posed in February by Senate Judiciary Committee Chairman Chuck Grassley and Flake, a panel member.

In recent years, DHS’ Immigration and Customs Enforcement has placed the highest priority on deporting dangerous criminals. The agency removed 315,943 people in the past fiscal year, including 177,960 who were previously convicted of a crime, it said.
