A 48-year-old woman was arrested this week after allegedly fatally shooting her former boyfriend in the lobby of a Harlem apartment building....26 years ago.

Police say Zunilda Rosario, 48, was arrested on Thursday after flying into John F. Kennedy Airport from the Dominican Republic. She is accused of shooting and killing 19-year-old Juan Deleon on February 11, 1990. Rosario had reportedly been fighting with Deleon—her former boyfriend and the father of her child—over his alleged infidelity, while they were in the lobby of a building on West 150th Street.

Deleon's body was found with gunshot wounds to the head and chest, but Rosario had disappeared—she apparently left New York with her two daughters, eventually moving to Providence, Rhode Island. She appears to have lived there ever since, working as a school bus driver. Deleon's murder was left unsolved, but in February a witness came forward and told investigators Rosario was guilty. After that, cops reportedly interviewed other witnesses who also said she pulled the trigger.

She is charged with murder and criminal use and possession of a firearm, and is expected to be arraigned later today.
