Skills / Techniques for a Police Sketch Artist

[JCurwen3]

What skills does a police sketch artist have / use?

Artist (Drawing) seems pretty important. But there's more to it - the directed questions regarding the appearance of the subject, capturing the appearance of a person they've never seen just from the descriptions of a witness / victim that may have (or think they have) a potentially hazy memory.

So how would you handle a situation where a sketch artist does their magic and sketches a fairly accurate image of a subject? What skills (and techniques) are involved, and how many rolls along the way?
