The show employs a variety of techniques to create the realistic-looking skeletal remains and forensic evidence:
* Props: Many of the bones and other props, like bullet casings, are made from specialized materials that resemble the real thing.
* Special Effects: The show employs visual effects and makeup artists to create wounds, injuries, and other details on the "bodies."
* Plastic Casts: The show also uses plastic casts of real human bones, which are then painted and textured to look realistic.
It's important to note that while the show strives for realism, it's ultimately a fictional drama, and using real human remains would be both ethically and legally problematic.
