She brought him up to Betty's room, where her body was, and asked Chief to dismember her.

Chief did as Dorothea asked.

Then they buried Betty's remains in the backyard.

And that apparently wasn't the end of Dorothea's plan, because soon after, Chief went missing.

And since he was a bit of a drifter, there were no official records of him, which meant the authorities had no way to find him.

Does Chief's potential murder suggest that Dorothea is probably paranoid?

And if so, has she gotten in over her head?

Or does she think her actions are maybe justified, even if they are punishable by law?

At the end of the day, Dorothea's desire for control overpowered everything else.

The fewer people who knew what she was up to, the more in control she felt.

But what she didn't realize was that there were people out there who were more determined than she was to protect the city's at-risk populations.

And soon, they'd beat Dorothea at her own game.

By 1987, 58-year-old Dorothea Puente had killed about seven people, maybe even more.

She'd buried most of her victims in the backyard garden of her boarding house, where she still cared for elderly and disabled tenants.

Then in 1988, Dorothea met the tenant who would change her life forever.

That year, a social worker named Judy Moise was looking for a new home for her client, 52-year-old Alvaro Montoya, who went by the nickname Bert.

Bert suffered from schizophrenia.

He sometimes heard voices, and on top of that, he mostly spoke Spanish, which made it harder for him to find stable, long-term care.

Until Judy found Dorothea.

Judy felt extremely protective of Bert, and Dorothea was one of the only people she trusted to care for him.
