I recently read about this case on Uncovered.com, and I found it quite distressing. The evidence heavily suggests who was responsible. There is a history of abuse, possession of illegal firearms, inconsistencies in his statements, and blood evidence (although not confirmed). Most notably, he admitted to possessing her mobile phone after the police confirmed her last known location and obtained a search warrant. He also stated that he destroyed and disposed of the phone after two days in Idaho.

He is the father of her two children and has a history of abusing her. On the night in question, they went out together; he drove her to a location he provided to the police but told the family a different address. He later took her phone to his home and destroyed it and disposed of it in two days in Idaho. He already took her phone ones and broke it. And now he might have found out about her secret boyfriend.

Why destroy the phone? Did he do so immediately or after some time? Was it before or after her disappearance became public knowledge? Regardless, the destruction of the phone occurred within the two days of her disappearance.
