Lincoln Lake Hiking/Bicycle Trail

There is a pretty good show being broadcast by our local PBS station called Exploring Arkansas; it features three segments describing locations of interest here n the state. Recently, they were discussing a place for mountain biking called Lincoln Lake. I checked it out on a map and found it was relatively close to where I live and decided to go "explore" it.
Surprisingly, I found it with almost no effort at all. I had already decided to hike it before trying to bike it. The hills here can be quite daunting. Sure enough, the hills were a bit more than I would like to handle on a bike. I was willing to hike it




But then, I thought better of it.


Don't know what the crime was, nor when, but I decided that this wasn't the place I wanted to be wandering by myself.

Is there a law about removing the crime scene tapes when the investigation is completed?
