From house wife to the big house.

Utah mom Kouri Richins — who fatally poisoned her husband, leaving their three sons effectively orphaned — is headed to the same prison where other notorious moms Ruby Franke and Megan Huntsman are housed.

Richins — who infamously wrote a children’s grief book after murdering her kids’ dad Eric Richins — will land at the Utah State Correctional Facility (USCF) within the next week after she was hit with a life sentence without the possibility of parole Wednesday, according to the state Department of Corrections.

A handful of notable inmates are serving sentences at the Beehive State prison complex — which opened in 2022 and houses both men and women at facilities of varying security levels.

Huntsman is serving a 15 years to life term at the facility located near the Salt Lake City International Airport after she pleaded guilty in 2015 to suffocating and strangling six of her newborn babies over the course of a decade.

The 51-year-old — who has three adult daughters — claims she was addicted to drugs and alcohol when she killed the babies, wrapping them in shirts, towel and plastic bags placed inside boxes in the garage of her Pleasant Grove, Utah home.

A seventh baby’s body was also found, but authorities believe it was stillborn.

Momfluencer Ruby Franke and Jodi Hildebrandt, who helped Franke torture her children, are also both serving hard time in the facility.

The 44-year-old host of now-defunct YouTube show “8 Passengers” pleaded guilty in 2023 to aggravated child abuse for starving and torturing two of her six kids by holding their heads under water. Hildebrandt — Franke’s former business partner — also pleaded guilty and is cooling her heels at USCF.

A few infamous men are also at the facility, including Dan Lafferty who is accused of killing his sister-in-law Brenda Lafferty and her 15-month-old daughter with the help of his brother Ron under the guise of a religious calling.

The murders are the basis for Jon Krakauer’s 2003 book “Under the Banner of Heaven” that inspired a Hulu show of the same name, starring Andrew Garfield.

Troy Michael Kell, a death row inmate and known white supremacist, is also in the facility for stabbing a fellow inmate 67 times, killing him. The 1994 murder was recorded on surveillance video, according to a report by KSL.

Richins was convicted of lacing Eric’s Moscow Mule with five times the lethal dose of fentanyl on March 4, 2022. She previously tried, but failed, to kill Eric two weeks prior by dosing his sandwich with the same drug.

Kouri and Eric’s three sons said they were terrified of their mom and begged a judge to keep her locked up for life in letters read to the court Wednesday.

Richins allegedly carried out the killing because she wrongfully believed she would inherit Eric’s $4 million estate, which would have cleared her real estate business debts and allowed her to start a new life with her handyman lover.
