These pieces of information would be helpful.
1. When and where was Rebekah last seen by a trusted friend?
2. When did she last report to work? Who saw her there? What did she say to her co-workers? Did she express any concerns, or did she tell anyone that she was was meeting up in Superior to collect her things?
3. When did she last use her credit cards and bank cards?
4. Her vehicle was recorded on security footage at the Town Pump in Superior. Is there any footage of her and/or Cerberus? If so, was she seen in or outside of her vehicle? If she was recorded driving away, did anyone follow her? Did she use her cards at the gas station?
5. What is the police history for the address where she was living in Missoula? There is a record of calls made to police attached to an address, or should I say this is what happens in other places. This would give details of any requests for assistance during the time Rebekah lived there.
