There was a similar case in Washington state, that of Michelle "Shelley" Knotek, who took into the home she shared with her husband and three children (each from a different father) a nephew and a couple of boarders who'd become estranged from their own families. All three of the boarders ultimately disappeared and Shelley lied to authorities and fabricated evidence to indicate they had left and were living elsewhere. In addition, Shelley briefly worked (before being fired and later court-ordered to keep her distance after being accused of menacing) for a company that provided care-taking assistance to elderly and vulnerable in their homes and one elderly man she'd met through that association died from a fall while in the care of one of Shelley's boarders. In his will, that man left Shelley his home provided she would take care of his dog until it died; she delivered it to a humane society and sold the house for the proceeds.
It was Shelley's children, who had been severely abused in the home and who also witnessed the abuse and severe negligence against the boarders and who were aware how their bodies had been destroyed after death, who repeatedly went to law enforcement to report what had happened in their home and eventually to urge that the youngest child remaining in the home be removed. That child was able to direct police to body parts that had not yet been converted to ash because the weather had not yet turned dry enough to allow a burn. They assisted author Gregg Olsen in telling the story ("If You Tell: A True Story of Murder, Family Secrets, and the Unbreakable Bond of Sisterhood") and the three sisters have expressed their concerns about what will happen when their mother is released in 2022.
