Brittany Murphy

A large number of prescription drugs were found in the bedroom of Brittany Murphy, who suffered shortness of breath and severe abdominal pain in the week leading up to her death, according to an investigator's notes obtained by TMZ.

Citing notes from the Los Angeles County coroner's office, TMZ said Investigator Blacklock wrote that Murphy, 32, went to the bathroom at 7:30 a.m. Sunday and shut the door. She had complained of shortness of breath and severe abdominal pain for seven to 10 days prior to her death, but her husband, British screenwriter Simon Monjack, told the investigator he wasn't alarmed because his wife "often suffered from severe menstrual pains," the site said.

Actress Brittany Murphy dead at 32

Assistant Chief Coroner Ed Winter, however, told TVGuide.com he has never seen the notes TMZ is citing and that the coroner's office has not provided the site with any notes or reports regarding Murphy's death and investigation.

"I have a call into TMZ, but we're not verifying anything [they say is] in the notes," Winter said. "TMZ won't show me what they have or what they've put in their story. ... We have an Investigator Blacklock. He is upset, too, because he never gave anybody anything or talked to anybody at TMZ either."

Winter said Blacklock was at Murphy's home with him on Sunday.

Calls to TMZ were not returned.

According to TMZ, the actress' mother, Sharon Murphy, checked on her daughter at 8 a.m. and called for help when she found Murphy unresponsive on the floor, the notes said. Monjack, who was in bed, ran to the bathroom, where he attempted to revive his wife by running the shower while Sharon Murphy called 911, TMZ reports.

Coroner: Brittany Murphy died of natural causes

The actress, however, remained "unresponsive and purged her stomach contents prior to the arrival of the paramedics," according to TMZ, which also said she had consumed noodles, leftover Thai food, Gatorade, and water and tea with lemon the night before she died. Murphy was "without signs of life" by the time paramedics arrived, TMZ said.

"Large amounts" of prescription drugs written to Murphy and "numerous empty" bottles of  prescriptions written to her mother, Monjack and other parties not named in the TMZ report were found on Murphy's nightstand when her body was moved to the master bedroom, the notes said.

The medications included Topamax (an anti-seizure medication also used to prevent migraines), Methylprednisolone (an anti-inflammatory), Fluoxetine (a depression medication), Klonopin (an anxiety medication), Carbamazepine (which treats diabetic symptoms and bipolarism), Ativan (an anxiety medication), Vicoprofen (a pain reliever), Propranolol (a hypertension medication, used to prevent heart attacks), Biaxin (an antibiotic), Hydrocodone (a pain medication) and vitamins, TMZ reports.

No alcohol containers or illegal drugs were found, according to the site.

No signs of foul play indicated in Brittany Murphy autopsy

The notes also say that Murphy had a history of hypoglycemia and was hospitalized in April 2009 for low blood sugar while on location in Oregon, TMZ reports.

An autopsy completed Monday showed no signs of foul play, but the cause of death has been deferred pending further tests.

As reports surfaced regarding the cause of her death, Murphy's colleagues continued to honor the late actress, including King of the Hill co-creator Greg Daniels. "Brittany was extremely kind, talented, funny, and in love with acting," Daniels told The Wrap. "She was a joy to be around. This is very tragic news."
