All very valid questions.
I was trying to track down the police report and there was one I found done on March 26th at 11:36am, but I can't be certain it is the right one without an exact address or more information. Ft. Worth does have online public records one can apply to obtain with a lot more info.
She must have been staying there with no running water or electricity. A visitor at 3:00am indicates she was either home or just coming home. Since she was familiar enough with the person nearby to ask if her friend could shower...maybe that same person allowed her to use the facilities, too? There was no mention of her BF in the theft report that I could determine, but weren't they together at the time? How long have they lived together? The way the article reads it is the same location they were sharing when she went missing unless I am mistaken.
Staying anywhere with no electricity and running water usually means no money to pay those bills for both to be turned off at the same time. However, if people were remodeling and perhaps not living there at the time or only stayed in a home seasonally...they would possibly turn them off. I don't see her having funds to do either one of those.
What are we missing here?
She knew the person and filed the report so I cannot imagine why there would not have been an arrest unless they could not find him again.
It would be interesting to know if he was known to the others in the Allen group at the apartment that night, too. If she knew him 8 years, wouldn't that mean the chances are pretty good he was from Allen?
