The Killer Who Stayed: Eight Days In Her House
Neighbors found 62-year-old Nilsa María Costa Pingi buried in her own backyard, dead for eight days. The man who put her there had been living inside her house the entire time, spending her money and showing no regrets. How could someone commit such an act against a woman who offered him trust and shelter?
In this episode, we analyze the chilling case of Nilsa Costa, a retired widow who opened her home to Leonardo Silva, the son of a friend. We explore the calculated steps that led to her death and the disturbing actions of her killer in the days that followed. What makes a person capable of such cold-blooded betrayal?
