Possible crime scene??

Posted by Bill Bill
Hi, I have a question for any CSI's here. I just stumbled in from google, sorry if this is misplaced.

I just moved into a new place. My room has concrete floors, in the basement. I noticed a spread of impact marks on the floor. Upon closer inspection I dug charred material out of many of them as well as a rusty BB or pellet. The paint is all stripped off in this particular area, which to me looks like it could be the rough outline of a torso and legs - also where most of the charred material is and most of the impact marks.

I have images here. Wondering if I should bring some of the charred stuff and BB in to the station. Something feels off. Not sure why there would be either impact marks OR charred material in them.
