Dorothea Puente operated a boarding house at 1426 F Street in downtown Sacramento, California, presenting herself as a caring landlady who took in elderly, disabled, and marginalized tenants, many of them referred to her through social services. Behind that reputation, she systematically murdered residents and continued to collect their Social Security and other government benefit checks after their deaths, forging signatures and diverting the funds for her own use.

Between 1982 and 1988, Puente is believed to have killed at least nine people, typically by drugging them with sedatives before they died. Her earliest identified victim was Ruth Munroe, a business associate who died of a codeine overdose in April 1982. Another early victim was her boyfriend Everson Gillmouth, 77, whose remains were found in a box along the Sacramento River in January 1986 but not identified for years. Most of her later victims were tenants at the F Street house, and their bodies were buried in the yard of the property.

The scheme unraveled in November 1988. Social workers and family had grown concerned about a missing developmentally disabled tenant, Alvaro 'Bert' Montoya, and on November 11, 1988, police and a federal probation agent came to the boarding house and began digging in the yard. They uncovered human remains, and over the following days investigators exhumed a total of seven bodies buried on the property. Puente, questioned but not immediately detained, fled Sacramento and was arrested days later in Los Angeles after a man she met at a bar recognized her from news reports.

Puente was ultimately charged with nine counts of murder. Her trial, moved to Monterey on a change of venue, began in early 1993 and featured lengthy jury deliberations that became among the longest in California history to that point. On August 26, 1993, the jury convicted her of three murders: first-degree murder in the deaths of tenants Dorothy Miller and Benjamin Fink, and second-degree murder in the death of Leona Carpenter. The jury deadlocked on the remaining six counts, which resulted in a mistrial on those charges; prosecutors did not retry them.

The jury declined to impose the death penalty, and on December 10, 1993, Puente was sentenced to two life terms in prison without the possibility of parole. She was incarcerated at the Central California Women's Facility in Chowchilla, where she consistently maintained her innocence and denied killing anyone, insisting the deaths were natural.

Dorothea Puente died in prison on March 27, 2011, at the age of 82. Because the case ended in conviction, it is not an unsolved matter; the recorded status reflects her 1993 convictions on three counts of murder. The six deadlocked counts, along with earlier suspected victims such as Ruth Munroe and Everson Gillmouth, were never adjudicated, leaving the full number of her victims a matter of historical estimate rather than legal finding.
