Los Angeles , California ( CNN ) -- An autopsy on the body of actress Brittany Murphy was conducted Monday , the Los Angeles County coroner 's office said . Authorities have said the 32-year-old appeared to have died Sunday of natural causes , and there was no sign of foul play or trauma . `` Naturally occurring diseases could be found in any person that could lead to death , '' said Capt . John Kades of the coroner 's office . The office is looking into Murphy 's medical history . A final report could take up to eight weeks . The cause of death will not be released until the toxicology report is concluded , said the coroner 's office . That process can take weeks . Police also are conducting an investigation , which includes robbery and homicide detectives looking at what was in her home , said Los Angeles Police Department spokeswoman Norma Eisenman . Murphy was pronounced dead at 10:04 a.m. PT ( 1:04 p.m . ET ) Sunday at Cedars-Sinai Medical Center in Los Angeles , hospital spokeswoman Sally Stewart said . She is survived by her husband , British screenwriter Simon Monjack , whom she married in 2007 . Statistics from the Centers for Disease Control and Prevention show the leading cause of death for American women in Murphy 's age range is unintentional injury . Malignant tumors are second , followed by heart disease and suicide . The often bubbly , free-spirited actress appeared in such films as `` Clueless , '' `` 8 Mile , '' `` Do n't Say a Word '' and `` Girl , Interrupted . '' She also lent her voice to animated works , such as the movie `` Happy Feet '' -- in which she also sang -- and a regular role on the animated TV series `` King of the Hill . '' `` The sudden loss of our beloved Brittany is a terrible tragedy , '' her family said in a statement issued by her publicist . `` She was our daughter , our wife , our love and a shining star .

Former boyfriend -- and `` Just Married '' co-star -- Ashton Kutcher was one of many celebrities to post his reaction to the news via Twitter . `` 2day the world lost a little piece of sunshine .

Singer-actress Jessica Simpson tweeted : `` Brittany Murphy was an incredible ray of Light to so many people . Her smile was contagious . My prayers are with her family and loved ones . '' Actress Alyssa Milano , who did a USO tour with Murphy in 2003 , wrote : `` She was a sweet soul , with a lot of talent and heart . '' Murphy was best known for her work in a string of romantic comedies earlier this decade , including playing lead roles in `` Uptown Girls '' alongside fellow Georgia native Dakota Fanning , and `` Little Black Book '' with Holly Hunter and Kathy Bates , but her movie roles had declined in recent years . Last month , Murphy was reportedly fired from `` The Caller , '' a movie she was working on in Puerto Rico . Her representative issued a statement to news outlets disputing the report , saying , `` She was not nor has she ever been fired from any job big or small . ... [ Due ] to creative differences Ms. Murphy and the production mutually parted ways , '' according to People magazine . Murphy was the subject of tabloid gossip after she transformed from a pudgy brunette in 1995 's `` Clueless '' to a petite , lithe blonde who graced the cover of such magazines as Cosmopolitan in 2005 . She frequently denied rumors of an eating disorder and plastic surgery . Her love life also was fodder for gossip sites as she broke two engagements in 2004 and 2006 , then married Monjack after four months of dating . `` All these ridiculous people came out and said all this nonsense when we got married , [ but ] thank God we had the substance and the history within that to [ say ] , 'Yeah , whatever ! ' '' Monjack told People in 2008 . `` We still do n't understand what happened . It 's made us laugh , it 's made us cry , but it 's made us stronger . ''
