Plot Synopsis

MURDERS AT THE BOARDING HOUSE is a two-part documentary that exposes the sinister scheme that grandmotherly Dorothea Puente (aka Death House Landlady) employed to rob her boarders of their lives and their money. Oxygen premiered this two-part special during its 2021 Serial Killer Week, premiering a new installment from 7-8:30pm ET/PT on consecutive nights to close out the week of programming:

Part 1 (Saturday, April 17, 2021 from 7-8:30pm ET/PT): When the Sacramento Police Department receives a missing person's report from a concerned social worker, they send Detective John Cabrera to the boarding house where the individual was last seen. The elderly landlady, Dorothea Puente, is friendly and cooperative, but when Cabrera discovers human remains in the backyard, Puente falls under suspicion of murder. Now, with police getting closer to unearthing the rest of the bodies, the old lady gives Cabrera the slip and goes on the run.

Part 2 (Sunday, April 18, 2021 from 7-8:30pm ET/PT): Detective John Cabrera must piece together the clues of Dorothea Puente's dark past to form a picture of the grandmotherly serial killer. Meanwhile, Puente is hiding out in an L.A. motel, and lining up her next victim -- an elderly man she meets in a bar. But when the man recognizes Puente's face on the news, he contacts the police and Puente is caught. Back in Sacramento, prosecutors embark on the case against Puente, and after a long, difficult trial, the judge sentences Dorothea Puente to life in prison.
