Norwich — The June 15 murder of Casey Chadwick brought the national debate over the failure to deport immigrants convicted of crimes to the region, as accused killer Jean Jacques, a Haitian national, twice was set free following prison terms without being deported.

Jacques, 41, has been held on a $1.1 million bond since Norwich police charged him with stabbing Chadwick, 25, at her Spaulding Street apartment. He faces a probable cause hearing in New London Superior Court on Jan. 12.

Chadwick's mother, Wendy Hartling, is demanding changes to federal deportation policies.

Jacques served 16 years in prison for attempted murder and was released in 2012 to the U.S. Immigration and Customs and Enforcement. He was set free after a failed deportation attempt. Jacques was imprisoned for about six months in 2014 for a parole violation and again was set free after ICE's attempt to deport him was thwarted by Haitian authorities.

U.S. Sens. Richard Blumenthal and Chris Murphy, both D-Conn., and U.S. Rep. Joe Courtney, D-2nd District, have called on the U.S. Department of Homeland Security's inspector general to investigate the case. During a recent Senate hearing, Blumenthal called the efforts to deport Jacques "abysmally and abhorrently inadequate."
