Reports state that Jackson received an injection of the powerful painkiller Demerol before his death. Police believe that injection came from Dr. Murray. Murray disappeared after the death, but resurfaced on June 26, 2009, and was reportedly set to be interviewed by police.http://www.tmz.com/2009/06/26/michael-jacksons-missing-doc-to-speak-with-cops/

According to Jackson's brother, Jermaine, Dr. Murray injected Jackson with demerol, then his breathing began to slow and eventually stopped.http://www.khou.com/news/local/stories/khou090626_mh_michael-jackson-houston-doctor.be3e4b2.html

After the death, police impounded Dr. Murray's car, which was a BMW licensed to Murray's sister, Susan Rush, in the state of Texas. Police believe the car may contain drugs or other evidence that can help with the death investigation.http://www.khou.com/news/local/stories/khou090626_mh_michael-jackson-houston-doctor.be3e4b2.html

The nature of the charges have not yet been released to the public.

Jackson's death was ruled a homicide, stating that he died, "from acute propofol intoxication," as well as, "...other conditions contributing to death."http://www.cnn.com/2010/CRIME/02/08/michael.jackson.charges/index.html?hpt=T2
