If the impact parameter and thus the falling objects angular momentum 
relative to the center of the black hole is large enough, the object
may go into a spiral into the center.  There is energy loss due to 
gravitational waves.  

	Chapter 33 of GRAVITATION by Misner, Thorne and Wheeler goes
into properties of black holes including charge and angular momentum,
but this is not an easy book to read.  It is a graduate level text and
it uses 1-form, 4 form notation rather than the more common tensor
notation
