Hi Lauryn, thanks for the update. This must be hard on you and your family. So the last known sighting is on Tuesday morning. Your father is seen leaving the hotel driving the car. Your brother is with him? They left their belongings & passports in the hotel, meaning they intended to return and they were probably not going far. The car has not been located either. If they disappered with their car, it could have been an accident. Something may have happened on the way to a rural property. If I understand you well, activities like hiking in the Sierra's, snorkling, diving and boating, all things like sports can be excluded?
