To their neighbors in Los Angeles, Olga Rutterschmidt and Helen Golay seemed like two kindly elderly women devoted to helping the city’s unhoused population. But behind their acts of charity lay a cold-blooded financial enterprise—and a trail of mysterious alleyway deaths initial law enforcement brushed off as routine hit-and-runs.

But when a persistent detective overheard a passing comment about a duplicate case file, a massive joint task force began pulling at the threads of their facade. What followed was a tense, high-stakes battle of wits between seasoned investigators, insurance fraud agents, and two master manipulators who refused to crack.

This week, we examine the subtle red flags, the undercover sting operation, and the tiny investigative slip-up that finally unraveled an unbelievable web of deceit.
