Summary
Lanny Horwitz built a life most people would envy—real estate success, international travel, the dream house in Boca Raton. But what he couldn’t seem to quit was his high school sweetheart. After two marriages, two divorces, and one seriously tangled family dynamic, Lanny and Donna found themselves under the same roof again.
What came next unraveled a story of long-term resentment, romantic triangulation, and a murder scene that made absolutely no sense. This episode breaks down the final days of Lanny Horwitz and the investigation that pulled his family—and his past—apart.
