It's best not to read and watch news as it could trigger you? That is gruesome to say the least. Try not to dwell on it, it is not a common occurrence.

I was on a bus going through the rockies at night last year..and the bus driver had a horrible movie playing (The Fog I think)... it could have set any unbalanced person off on the moonless night... one reason I didn't go back out this year, as I needed to do it differently and couldn't coordinate it yet.
