Just last night I had the opportunity to view taser marks that had been applied to a female the day before. Here are the circumstances:

The female weighs 115 lbs and was handcuffed at the time, but was experiencing a psychosis and on the way to the emergency room a taser had to be used. The taser was applied to her while she was struggling, in the area just below her right breast, and the electrodes entered through a t-shirt and a heavy sweatshirt. The marks were constant and round and did not spread. They looked exactly like those on JonBenet.
