Unfortunately, the most likely explanation IMO is damage to the cylinder wall 
or piston.  Might be just a broken ring, or badly worn valve guide, though.

Rather than mess with a compression test (which can sometimes be misleading), I 
would go ahead and pull the head to check the valve.  Your friend knows he has 
a problem, and he will need to pull the head anyway, even if the problem is 
rings/piston/cylinder wall.  And it's worth checking the valves when the head 
is off even if they aren't the primary problem.
