“In horrible situations like this, we do everything we can to help the victim,” Detective Chase Nash said in a Friday morning statement provided by the police department. “We are here for the long haul. Whatever they need.”

The documents do not state how police began investigating the case.

One of the woman — who was in a relationship with Sanchez for years, when she lived in a different Wyoming town — said that about 15 years ago, after years of abuse, Sanchez beat her and threatened to kill her if she did not leave a house they shared, according to the documents. She spent a mid-winter night in an open garage, she told the detective. Sanchez was later convicted of reckless endangerment, the documents state.

The second woman described to police a pattern of abuse largely similar to that described by the other survivor, who now lives in a different state, according to the documents.

The woman said that shortly after she and Sanchez became involved, about 15 years ago, Sanchez became possessive and controlling, according to the documents. She told a detective that Sanchez made her strip naked in his NOWCAP office, the documents state. At home, she said, Sanchez beat her, and when she fell, kicked her as she lay on the ground.
