I would call 190# near 200+
for durham62: I'm sorry your friend got shot. But he was an idiot who was doing WRONG and paid the price. As someone else pointed out above, he was committing "malicious mischief" also called disturbing the peace. Granted that its a misdemeanor and he probably shouldn't have been shot, I'll not fault the homeowner without knowing ALL the facts.
Also, i forgot to mention that saying Mark was 6'2" 210lbs is a gross exaggeration. He was close to 6'0" and maybe 190 at most.
I'm sorry for his loss but his comment makes the estimation at a 10% error for the weight and less for the height.
If he wore the type of clothes that I have seen on some teenagers, I could see myself overestimationing by as much as fifty pounds.
