Electronic security tags — small, ankle-attached transmitters — were developed and deployed widely in maternity wards beginning in the late 1980s and through the 1990s. These tags trigger alarms and, in some systems, automatically lock elevator and stairwell doors if an infant is carried toward an exit. They are now standard equipment in most American hospitals with obstetric and newborn units.
Access control systems for maternity and newborn units were tightened. The open-access model that had allowed Pettway to move through the ward and interact with patients and families was replaced with badge-access or staff-only entry requirements at most facilities.
NCMEC’s Code Adam alert system, developed in 1994, provides a protocol for immediate lockdown and systematic search of a facility when a child is reported missing. Originally developed for retail environments after a child disappeared from a Florida Walmart, the system was adapted for hospital settings and became widely adopted in the following decade.
Whether Harlem Hospital specifically faced any formal review, remediation, or institutional consequences in connection with the 1987 abduction is not established in sources available for this article.

## The Twenty-Five-Year Anniversary and What It Marked
Ann Pettway was sentenced on July 30, 2012 — just days before the twenty-fifth anniversary of Carlina White’s disappearance from Harlem Hospital. That timing was noted in coverage of the sentencing.
Twenty-five years is a long time in a person’s life. Carlina White was twenty-five. Joy White was in her late thirties. Carl Tyson was roughly the same age. The anniversary of the night a baby went missing from a crib was now also, in some sense, the anniversary of a theft of time — twenty-three years in which a daughter did not know who she was, a mother did not know where her daughter was, and a father carried the weight of a loss that could not be meaningfully resolved.
