Just as long as people read the story and understand that the composite drawing is several years old. He probably doesn't have those long sideburns anymore for one thing. I think the best thing for a person to do is study the drawing and mentally remove the excess hair on his face but keep in mind that he probably still has very thick eyebrows and a stocky build. Maybe we should call it a stalky build.
It's still not a lot to go on because that description fits a lot of guys. Kelowna to Armstrong isn't all that far so he's probably still in the area.
There is some vague familiarity to the drawing but as I said - the description and also the drawing could match a lot of people.
