Brittany Murphy might have been poisoned

Brittany Murphy may have been poisoned as retested samples showed the presence of high levels of heavy metals, according to a new toxicology report.

Rat poison may have been the cause of death of the 'Clueless' star, Fox News reported.

Murphy's mother had found her dead at home in 2009 and was ruled dead due to pneumonia and anaemia by the Los Angeles Coroner.

This was followed by her husband, Simon Monjack's death due to the same cause, five months later.

However, when her father, Angelo Bertolotti ordered an independent report, it was found that the reason of her death was not a natural cause, and it even suggested that the couple could have been murdered by a third party.

Bertolotti was able to obtain samples of her hair, blood and tissue for testing after years of proceedings and had ordered testing for heavy metals and toxins.
