The cornerstone of any shooting reconstruction is determining the muzzle-to-target distance. When a firearm is discharged, unburned gunpowder particles and soot are expelled. If the gun is pressed against the skin (a contact wound), the residue is driven into the wound, and the skin often shows a distinctive muzzle imprint. If fired from even a few inches away, a halo of stippling (abrasions from powder burns) appears around the entry hole.

Blood doesn’t lie, and it doesn’t follow the rules of gravity unless forced. The bloodstain patterns in the closet were inconsistent with a self-inflicted wound. When a standing person suffers a fatal gunshot, they collapse in a predictable pattern, creating cast-off and pooling that matches their fall.

In 2017, based almost entirely on the reconstructed physical evidence, Michael Plotkin was arrested. He was convicted of second-degree murder in 2018. The conviction was a landmark victory not for a new DNA test or a snitch, but for the enduring power of crime scene reconstruction. The Sharon Plotkin case serves as a masterclass in forensic integrity. It reminds investigators that a crime scene is a three-dimensional puzzle of physics, biology, and geometry. The initial "clean" suicide scene was, in fact, a chaotic homicide that had been poorly rearranged.

In the Plotkin closet, investigators noted high-velocity spatter on the closet door frame and interior walls—spatter that would only occur if Sharon was standing at the doorway, not kneeling or sitting in the back of the closet where she was found. Furthermore, the absence of significant blood on the inside of the closet door suggested the door was closed before the bleeding occurred. The reconstruction suggested a sequence: Sharon was shot near the doorway, then her body was moved or collapsed deeper into the closet.
