A Rowlett police officer said he was shocked that a sketch he drew led to a capital murder arrest
McKinney police called Officer Ray Clark's drawing instrumental in leading detectives to Kosoul Chanthakoummane, who was with the stabbing death of real estate professional Sarah Ann Walker.
Clark said while he has done a lot of drawings, less than half led to a suspect. But authorities said Clark's most recent sketch was dead on, and they believe it helped them solve the high profile murder.
Two weeks ago, Clark met with a witness who described seeing an Asian man in his 20s driving through the same Craig Ranch neighborhood where Walker was found stabbed 27 times. Clark said the witness thought back the best he could and helped the sketch artist put features on a piece of paper that resulted in a drawing that was at least a likeness to the person that he had seen.
With the help of a book containing 960 different photos of everything from ears and eyes to scars and skin, Clark was able to sketch a man known as "a person of interest" to the case.
Another witness saw the sketch, and led police to Chanthakoummane.
"It narrowed it down enough to trigger someone's memory who had seen this person and knew who he was," Clark said of the sketch.
Clark said while he is sketching, his goal is to come up with a drawing that's 70 to 80 percent accurate.
The Rowlett artist and officer said his sketches are only as good as the witness who gives the description.
