The court website is lasuperiorcourt (dot) org. Case # is BP117321. As for your question, I don't think the LAPD is investigating a "homicide." The LAPD website says as of 08/28/09, "there will be no further updates regarding this investigation." I think the LAPD initiated the hoax in order to conduct a DEA sting operation in conjunction with the DEA and also to possibly unravel a murder plot because Michael had clearly stated he was "scared for his life."
Below are two articles that CNN keeps deleting every time I post them. The first is from a case in Florida where the police staged a murder and leaked it to the press in order to unravel a murder plot. The article can be found here. Just copy and paste in your browser and take out all the empty spaces and replace the (dot) with a real dot.

The second one I have posted is from Russia where the same thing happened, police staged the murder and leaked it to the press. That article can be found here. Again, you must take out all the empty spaces and replace (dot) with a real dot.

It happens a lot and there are many, many other articles that can be found where the police have done the same thing.
In my opinion, this is why there is no ongoing investigation or update on the investigation into Dr. Murray. He played the "role of the informant" to kick-start the DEA sting operation and possibly the investigation into unraveling the murder plot if there indeed was one.
