On an August evening in 1982, children playing in Boston’s Franklin Park stumbled onto a scene that would quietly become one of the city’s most troubling unsolved cases.

The victim was a 16-year-old girl who had already endured instability, displacement, and independence far beyond her years. Her murder received little attention at the time, but within months, rumors began to swirl: allegations of sexual assault inside a private police club, whispers of a cover-up, and a detective who refused to back down.
