I didnt keep posting in the thread, cause I felt bad...didnt want it to seem like I was coming down on the kid or anything. But, if Ophiura is wondering too, I'll go ahead and say what I was going to, yesterday.
My first guess would be internal parasite or some other type of disease. It's quite possible that you passed it onto the second snake from handling both, etc. It's kinda odd that two different snakes would die in a very short period of time, without the two deaths being connected.
What were you feeding? What type of enclosures were they in, with what substrate, etc.
Until you confirm the reason for death, the last thing you need to do is go and buy another reptile.
