Is law enforcement sure the final text msg. was sent by her? Is it possible or probable it was sent to buy time?
Did the person last seen with her have a previous relationship or knowledge of who she was? Why would you leave a young lady who appeared to be suffering from some type of distress (according to report details) to go check on horses leaving her alone in your home?
Did she have a history of running away or leaving for multiple days or was she a responsible person with a normal relationship with family.
Why contact her ex bf was their breakup a surprise had she recently met someone new?
How would the guys seen with her last react to being rejected if they had tried to flirt or hit on her? When the person left was she relaxed and calm enough to remove her own shoes? Was there any type of accelerant found on the couch causing the fire, if someone started a fire would they then remove their shoes then leave their other personal items behind. How far could a barefoot young lady run before her feet got to a point she couldnt run any farther? Why was the item that was set on fire? It does destroy biological evidence (just a thought not making accusations).
