Almost five years after a harrowing discovery shook a Bronx community, a woman has been apprehended in connection with the murder of twin newborns found dead outside an apartment building, their umbilical cords still attached. The 36-year-old woman, Stephanie Castillo, was taken into custody on Friday and now faces murder and manslaughter charges. Castillo, who once lived with her parents in the building where the children were discovered, was linked to the crimes by DNA evidence. According to ABC7NY, her parents, unaware of their daughter's pregnancy, still reside in the same building and have participated in annual vigils to honor the children.

Determined NYPD detectives relentlessly pursued this case, now spanning half a decade with no significant leads or surveillance footage to assist them. The case saw a breakthrough when detectives managed to eventually link Castillo to the infants through advanced DNA analysis. As a result of the tireless investigation, Castillo was arrested after departing from a homeless shelter in the Bronx. "My heart is really hurting, really hurting right now," neighborhood resident Michele Frasier told ABC7NY, echoing the collective grief of a staggered community.

In a separate report by the New York Post, the twins, posthumously named Zeke and Zane by NYPD officers and homicide detectives, were given a funeral by nearly 20 officers who never ceased in their quest for answers. The genetic evidence trail eventually led to Castillo, linking her directly to the crime scene.

Forensic evidence, inclusive of blood from the suspect and children, was pivotal in reconstructing the events that led to the twins' demise. Moreover, one of Castillo's relatives indirectly contributed to the arrest through a genealogical DNA database. NYPD Assistant Chief Michael Baldassano underscored the department's commitment: "Every year they had a memorial for these two children. They have never stopped caring about this case." Moreover, an inadvertently discarded drink container by Castillo helped police to decisively match her DNA with the suspected killer's profile. In a statement obtained by the New York Post, Renford Cole, a super who discovered the bodies, expressed palpable relief upon the arrest: "I'm so happy to know that they find the person because those were babies, innocent babies," he said, underscoring the emotional toll the case has taken on all those touched by the tragedy.

Castillo, now in custody, was purportedly living in near proximity to the College Avenue building in a shelter before her arrest. Assisting the NYPD in the arrest were agents from Homeland Security Investigations. The familial DNA that finally brought the case to its denouement serves not only as a testament to the determination of law enforcement but also as a somber reminder of the profound loss felt by the community and the officers who have silently borne the weight of this case for years. "Today is a very good day," Cole told the New York Post, marking a moment of closure that has been a long time in coming.
