The three moved to Idaho Falls in March and lived together with Martinez. When they moved to Idaho Falls, Martinez became Balderas new girlfriend while Zamudio and the victim, both of whom were his exes, continued to live with him.

The victim told police she had been tied to the chair once before, two weeks before the incident, when she also had her hair cut. She said Martinez cut her hair and told her she did not deserve it. Martinez accused the victim of disrespecting her and stepping on her toes, according to the probable cause affidavit.
