I find myself unable to watch all of the trial, though I'm trying to keep up. We have a TV channel we can watch over the air with our regular antenna, but you can watch it via several different online sources. These are today's links to live coverage: PBS News Hour; Now This News; ABC; CBS News; NBC News; Law and Crime Network
I hadn't seen the full video of the killing before the first day of the trial and offer this link to it here with the warning that it's hard to watch.
You can see video and voice-over description of the events in this video:
