In February 1987, following a bombing in Salt Lake City, Utah, a suspect sketch of the Unabomber was released, depicting the suspect clad in a hooded sweatshirt and sunglasses, a look that became synonymous with the case. When Ted Kaczynski was eventually apprehended, his appearance bore a clear resemblance to this police sketch, highlighting the accuracy of the artist's work and playing a significant role in the public's recognition of the Unabomber, aiding in his capture.

The Rise of Composite Photos

Composite photos, a critical tool in criminal investigation, are created using descriptions provided by witnesses or victims to visually represent a suspect's appearance. These images, often pieced together using computer software or sketched by an artist, play a vital role in generating leads, particularly in cases with limited physical evidence.


While police sketches may not always display a spitting image of the suspect, their role in stimulating public engagement and recognition and providing leads in challenging cases is undeniable. This blend of art and detective work, although imperfect, remains a valuable tool in law enforcement's arsenal, offering aid in the pursuit of justice.
