Jaconias Rosa Pereira, 50, is a citizen of Brazil. He entered the United States at an unknown location on an unknown date without being inspected by a U.S. immigration officer.

In August 2022, the Enforcement and Removal Operations (ERO) of the U.S. Immigration and Customs Enforcement (ICE) in Boston, Suffolk County, Massachusetts, USA was notified that Rosa Pereira was the subject of an open arrest warrant. He was required to serve a 15-year sentence for a murder conviction brought by law enforcement authorities in Brazil.

On December 28, 2022, officers with the ERO field office in Boston arrested Rosa Pereira without incident near a residence in Worcester, Worcester County, Massachusetts. It is unclear whether or not he lived there.

Rosa Pereira will remain in ICE custody, pending immigration proceedings. He is scheduled for a court hearing with an immigration judge with the Executive Office for Immigration Review (EOIR) of the U.S. Department of Justice.

Created on January 9, 1983, the EOIR is an agency within the U.S. Department of Justice that is responsible for adjudicating immigration cases. It is separate from the ICE and the Department of Homeland Security.

Immigration judges in these courts make decisions based on the merits of each individual case. ICE officers make enforcement decisions on a case-by-case basis and carry out the removal decisions made by the federal immigration judges.
