The coroner's findings do not necessarily mean charges will be filed.

Sources familiar with the multiagency investigation have stressed that a manslaughter prosecution is not inevitable, given Jackson’s history of drug use, health problems and other challenges in the case.

...Homicide refers to a death at the hand of another person, but does not necessarily translate to criminal charges. In court papers, the Los Angeles Police Department has identified Dr. Conrad Murray, Jackson's personal physician at the time of his death, as the target of a manslaughter investigation.

Dr. Murray has been cooperating with police. According to search warrant affidavits in Houston, where Dr. Murray lives,

Murray said he resisted -- fearful that the pop star had developed a dangerous addiction to propofol. Instead, Murray administered the sedatives Valium, lorazepam and midazolam -- five times over six hours. But none put Jackson to sleep and he continued to demand his "milk," the word the doctor said the pop star used for propofol.

According to Dr. Murray, he finally acceded to Jackson's request and administered the propofol at 10:40 a.m.
