Stay off the Grass, ya Black Dahlia Sillies!

"Please stay off the lawn," the tour guides said. "In fact, stay off the sidewalk. And please don't do what someone did, the first time we gave this tour, and lie on the grass.
We stood in a nice suburban neighborhood. You'd never guess anything ugly  had occurred 64 years earlier.
I was on Esotouric's  The Real Black Dahlia  tour, visiting  locations associated  with  one of the one of Los Angeles's most infamous unsolved murders. 
The guides tactfully steered us just south of the where the body (which was cut in two) was found in 1947.  I think they wanted to point out the location without having us stomp all over someone's property, as it lies on what is now someone's front lawn, right next to the sidewalk.
Later I did some Google searching and discovered some visitors (and there are plenty) aren't so thoughtful.  The case has a cult following and some people have spread out on the grass and posed for pictures.  What the hell!?

 

I wonder how often it happens?  What's it like to live there*?  Do the residents get mail addressed to the victim?  Do people leave flowers and plush toys?  Do crazy people knock on the door and ramble on about the case?
Does the scene below ever happen?:

If this were my lawn, it would happen.
Or maybe I'd just charge each weirdo five bucks per photo.

*The house was built about nine years after the body was found.   Rumor has it that the builder (or original owner) was obsessed with the case, if not personally involved, which I find hard to believe.  Looks like a regular tract house to me.
