During her testimony in the Michael Jackson trial, investigator Elissa Fleak admitted that she made mistakes when collecting evidence, such as medications, from Jackson's bedroom after his death in June 2009.

While Fleak did not deny making some reporting errors, she did make the argument that most crime scene investigations are imperfect. We can't argue there; there is no escaping possible human error, inadvertent or not. This isn't small screen 'CSI,' folks!

According to The Associated Press, via Billboard, Fleak said she found a bottle of meds on the floor, but the same item was photographed on a nightstand, so she seemingly bungled the details pertaining to where she found bottles of pills and such.

Another glaring error? Fleak did not make note of the fact that she had found propofol, the anesthetic that killed Jackson, until two years later in March 2011.

She admitted that the investigation was imperfect, but did not cop to making "substantial mistakes." She
also said she has never had a perfect investigation.

Fleak also testified that she was dispatched to the scene on June 25, 2009 and that she returned to the location several days later to follow up on leads that Dr. Conrad Murray, who is on trial for manslaughter, had provided to the police. She said that returning to the scene is not a typical action.

There's more damaging evidence against Murray, whose defense team alleges that Jackson self-administered the fatal dose of propofol. The singer's fingerprints were not found on any medicine bottles but Murray's were.
