IMO, the rings being left home are a telling piece of evidence. I dont think any woman would deliberately leave her rings at home even if she was planning on leaving someone. I would say the rings were removed from her finger after death and either left home or brought back home to make it look like she just ran off! Those rings could have been checked for fingerprints to tell if someone other than her had handled them! Did LE think to do this? Lots of little telltale things of evidence that im not sure was even thought of in this case! Even if Jenn were going to meet someone she had met online, she would have left her rings on and just taken them off and put them in her purse, it seems to me!
Saw one case on ID where the husband murdered his wife in a fit of rage.. He removed her valuable diamond wedding ring set, and then placed a much cheaper plain gold wedding band on her finger before disposing of her body.. The husband was later convicted for her murder.
I could see this scenario happening very easily in this case...jmho
