Police arrest teen in connection to East Boston homicide

Boston police have made an arrest in the killing of 18-year-old Blanca Lainez, who was found beaten and stabbed to death in June in East Boston.

Construction workers found Lainez’ body on a pile of 2×4 boards in a garage behind 54 Princeton St. on the morning of June 15, according to the Suffolk Country District Attorney’s office. Shewas pronounced dead at the scene.

On Sunday, authorities arrested East Boston resident Jose Hernandez, 16, and charged him with murder.

Authorities used a combination of phone records, surveillance images and forensic evidence in the case. According to prosecutors, “analysis of Lainez’ cellphone showed ‘extensive contact’ between Hernandez and the victim prior to her homicide and suggested ‘animosity’ between the two. Hernandez had threatened her in the weeks prior to her death.”

“This arrestreflects a nonstop investigation into a crime of brutal violence,” Suffolk County District Attorney Daniel Conley said toBoston.com.”But that investigation is still very active, and we urge anyone with additional information to share it with police and prosecutors.”
