Like a few others on here, I am having a real hard time ruling the husband out until they can be 100% sure on his whereabouts in the early morning hours of Saturday. I think he became jealous despite their separation. He is trying to deny marital problems all together and that makes me think he's got something to hide. Too many people saying there were marital problems and that he moved to Florida. I don't want to read too much into the Facebook happenings (her pics removed then added after the fact). However when chief can only say "We were told he was in Florida", that tells me that they are still looking into it. One theory could be that they had a conversation at 3 on Friday. It was encouraging to him and he decided to surprise her that night. Then became enraged when she was out then an argument went bad. Sure Mapquest says 8.5-9 hour drive, but from my experience (and at that age drivers are usually willing to exceed speed limit) you can take up to 40mins off of that long of a trip. He could have been sitting there fuming for a bit waiting for her to come home. Just a theory, not saying I necessarily believe it.
