Here's what I think happened based on previous
experience with GM AC systems:

The screen in the dessicant/drier assembly broke and
released the dessicant beads all through your system
which jammed the compressor. Unplug the electrical
connector from the compressor to disable the clutch
and you'll be able to drive it home. Once home, take off
the belt, engage the clutch with jumper wires (polarity
doesn't matter) and turn the pulley by hand. If you feel
gravel in either direction, then this is what happenned.

In this case you'll need a new compressor and drier
assembly, the system must be flushed and you'll need
to clean the gravel out of the orifice tube (just upstream
of the evaporator coil (the cold one).

Hope this helps
