Today I had a quick look at the horoscope of actor Julian Sands, who disappeared on January 13 of this year.
I didn’t find anything very spectacular, but on the day of his disappearance there was a sesquiquadrate between the Sun and Mars, and this sesquiquadrate was hitting his natal Mars. So the disappearance does seem to be a Mars event.
I therefore don’t think he got lost and died of exposure. I think it more likely that he had an accident, or was the victim of an assault, whether by an animal or a human.
