BOSTON — A second person has been arrested in Boston in connection with the stabbing death of an 18-year-old woman who had come to the United States from El Salvador two years ago hoping for a better life.

Boston police charged 21-year-old Angel Ramos of East Boston with murder Friday. He was detained pending a court appearance later in the day.

Blanca Lainez was found dead June 15, two weeks before her 19th birthday, in a garage in East Boston. Relatives said she arrived in Boston in 2014 after a dangerous trip from her native El Salvador to the Texas border.

Police in July charged 16-year-old Jose Hernandez of East Boston with murder in Lainez’s killing.

It wasn’t immediately clear if Ramos has a lawyer who could respond to the allegations.
