Los Angeles: American actress Brittany Murphy's mother has launched a fresh legal bid to prove that her daughter was killed by toxic mould.

Sharon Murphy has insisted that the defects at the late actress's Beverly Hills home led to her death from pneumonia two years ago on December 20, 2009, and her husband Simon Monjack's passing five months later, as reported.
However, she previously accepted a settlement from builders for the faults, but claimed her lawyers failed to tell her she was waiving her right to sue for "wrongful death".
She has now enlisted the services of attorney Michael Marzban to sue her former legal team for malpractice, and is seeking the amount she would have won had she pursued her previous action, plus other damages.
