A Jackson family source says that despite a recent collection of reports claiming that Michael's mother, Katherine Jackson, is convinced of foul play in her son's June 25 death, "there is neither a plan nor a need for another autopsy."

But it's not that another autopsy is unplanned and unnecessary. It may also be impossible, thanks to the current state of the music star's remains.

All tissues and samples, including his brain, were already removed, making Jackson's body more or less "a shell" of little or no forensic value.

Gliniecki says another autopsy "would be totally pointless," thanks to the detail that went into the first examination of the late icon's body.

The results of which are indefinitely delayed.

The legendary Michael Jackson (1958-2009).

"Especially in a high-profile case like this, [the first autopsy] was probably done very well. We can still run more tests, but the toxicology results are compromised because they replace blood with embalming fluids. It changes the chemistry."

"During an autopsy, everything is sliced and diced ... and everything mixes together. Even a second autopsy is significantly compromised."

Police and DEA agents continue to investigate Dr. Conrad Murray, Michael's personal physician, and his role in Jackson's untimely demise.
