Icicled Eaves, Missoula, Montana

I remember a story - possibly a big sister’s bedtime story - about a mysterious winter stabbing murder. Neither murder weapon or murderer were ever found, and there were no clues to aid the investigation - just a small pool of water next to the body in the narrow side yard at the victim‘s home. Well, as you may have deduced by now, the clever solution to this morbid tale is that gradually warming temperatures caused a huge icicle to fall from the eaves - and subsequently impale the victim as they walked along the side of their house. The icicle then inconveniently melted.

I don’t think I slept very well on the heels of that nighttime tale. 
And I’m still very careful while navigating near icicled eaves.
