NEW YORK — Federal immigration authorities say a man accused of killing his ex-girlfriend and dumping her body in a suitcase in Connecticut is a citizen of Portugal and is in the U.S. illegally.

Officials with Immigration and Customs Enforcement said Wednesday that Javier Da Silva Rojas entered the United States in May 2017 through a visa waiver program and was supposed to leave the country later that year.

Da Silva is charged with kidnapping resulting in death in connection with the killing of 24-year-old Valerie Reyes. Her body was found in a suitcase in Greenwich on Feb. 5.

A lawyer for Da Silva declined to comment Wednesday.

A funeral for Reyes was held Wednesday in her hometown of New Rochelle, New York.
