Former criminal prosecutor and true crime investigator Loni Coombs says when she learned about Montana’s crisis of missing and murdered Indigenous women, she wanted to find out why so many cases remain unsolved and, at times, even overlooked. In a new documentary airing on Oxygen, “Murdered and Missing in Montana,” Coombs tries to find the answers.
 
“[The statistics] are such epic proportions; I think it’s overwhelming. People can’t even get their mind around how horrific this is,” Coombs tells Dr. Phil on Tuesday’s episode. “I went in to look at three specific cases, and in each one of them, the lack of response was shocking in two different areas.”
 

Hear more about what Coombs discovered in the video above. And, Paula and Nate, whose 14-year-old daughter, Henny Scott, disappeared and was found dead, share what happened when their daughter’s body was found.
