Cathy Terkanian was happily married and living in Massachusetts but would often think about the smiley, blue-eyed baby girl she had given up for adoption when she was a teenager - hoping she was having a good life.
Then, after years of wondering, she made the shocking discovery that her daughter, Alexis Miranda Badger, had in fact been murdered by her adopted father, Dennis Bowman, who dismembered her body and buried her in a shallow grave in the backyard of his Michigan home.
Now Terkanian, who is featured in Netflix's Into the Fire: The Lost Daughter, tells the Daily Mail the true horror of discovering that her daughter, re-named Aundria Bowman, had been placed with a serial killer.
'There were a few people my daughter grew up with who told me quite a few graphic details... terrible things,' she said.
'I think he (Dennis) was molesting my little daughter at a very young age,' she added.
