Brittany MurphyBrittany Murphy was very ill in the hours before she went into cardiac arrest and died, sources tell TMZ.

We're told Murphy was taking prescription meds for flu-like symptoms she had been experiencing for several days. We're told Murphy began vomiting early Sunday morning and told family members she was feeling very ill.

Sources say various prescriptions were found in the home -- written for Brittany Murphy, husband Simon Monjack, and Brittany's mom. One source says, "There were a lot ... a lot of prescriptions in the house."

Law enforcement sources tell us Murphy collapsed in the bathroom and somehow ended up in the shower ... there was, we're told, a significant amount of vomit in the immediate area.

We're also told authorities did not find illegal drugs in the house, but Murphy was definitely taking various prescription meds.

Sources say her condition and the meds could have triggered a heart attack, but it's too early to know. An autopsy is will be performed Monday or Tuesday. We reported earlier Monjack did not want an autopsy but ultimately it's the Coroner's call.

As we first reported, Brittany Murphy's mother told paramedics her daughter suffered from diabetes. We're told it was type 2 diabetes and people involved in the case doubt her condition caused her death.

The scene Sunday outside the Los Angeles home of Brittany Murphy

Brittany Murphy's sudden death at age 32 is under investigation by the Los Angeles County Coroner's Office, which will conduct an autopsy "as soon as possible," an official tells PEOPLE.

No cause of death has yet been determined, but according to coroner's Capt. John Kades, "Foul play is not suspected at this time because there were no outward signs of trauma or other injuries."

Murphy was "found unresponsive" in her home in the hills above West Hollywood on Sunday morning, Kades said. Paramedics transported her to Cedars-Sinai Medical Center, where she was pronounced dead at 10:04 a.m.

"We don't have an autopsy scheduled yet, but we will do it as soon as possible," Kades said. "Given all the worldwide attention, if we can get it done [Monday], we will."

A toxicology test looking for the presence of alcohol and drugs will also be conducted, but the results will not be available for weeks.

Los Angeles police detectives also arrived at Murphy's house in what a police spokesman called a "routine" death investigation.

One of Murphy's neighbors said that paramedics were inside her house for nearly an hour before she was taken to an ambulance on a stretcher.

"One paramedic was still working on her," said the female neighbor. "First, I couldn't even tell that it was Brittany that was on the stretcher. I looked like an older woman. Brittany was completely white and her face was covered with a mask. You could tell that something horrible had happened."
