Shanann Watts' brother has urged Netflix users to watch the film about her tragic death.
American Murders: The Family Next Door tells the horrifying true story about how Shanann's husband Chris murdered her and their two little girls, Bella, four, and three-year-old Celeste, in 2018 after cheating on her with another woman.
Now Shanann's sibling Frankie has praised the show for "giving her a voice" as he told people to see it if they want know the true story.
Writing in a Facebook post, Chris said: "I highly recommend watching this. It's on Netflix. The director made sure we were a part of the whole process and we met the whole team personally.
"They made sure we were okay with them making this before they even started, unlike Lifetime's horrible movie.
"This documentary gives my sister a voice and she speaks throughout it.
"It also shows what her life was like before he came along and how happy she was with her beautiful family until he cheated and turned into a different person and became that monster."
He added: "How crazy that even Kylie Jenner watched it and shared this on her Instagram.
"My sister is an inspiration to millions of people all over the world and I'm honoured to be her little brother.
"She's still changing lives and I couldn't be more proud."
The Netflix film showed how Shanann's friend called the police to report her missing, with Chris initially suggesting that she had walked out on him.
After failing a lie detector test, Chris confessed that he killed her and drove her body to his old workplace with his two daughters in the back.
It was there that he killed the toddlers and put them in an oil tank, before burying Shannan, who had been pregnant, in a shallow grave nearby.
