Nancy Motes, Julia Robert's half sister, left a five-page suicide note suggesting the Oscar-winning actress was responsible for her death.

Motes' body was discovered by her finace  in a bathtub in the house where she was pet-sitting, reported  NY Daily News. Along with the body, both prescription and non-prescription drugs were found at the scene. Another update from the news site reveals that  Motes left a five-page suicide note suggesting the Oscar-winning actress was responsible for her death.

"It was definitely a suicide. She left a five-page suicide letter. The EMT found it," a source reportedly told the newspaper. "There were three pages of rantings that her sister drove her to do this. There was one page to her mom, telling her how much she loved her, and one page apologizing to (her fiancé John Dilbeck)".

Motes was a professional dog walker and pet sitter operating in the area. She was also a production assistant and reportedly didn't get along with her famous half-sister. Last August, during an interview with NY Daily News she claimed that Roberts teased her about her weight when they were younger. However, she did reveal that the two are trying to mend their broken relationship though it's still a "work in progress."

Just days before Motes' death, she went on a Twitter rant, calling Roberts all sorts of names and claiming that she was "cruel."

"So my 'sister' said that with all her friends & fans she doesn't need anymore love. Just so you all know 'America's Sweetheart" is a B***H!!" one tweet read.

"Do you want to be a fan of someone so cruel? She's not even that good of an actress. Happy you totally F***ed with me?" read another tweet.

"I must admit I maybe going to far... But I never been so angry in my life. I'm actually a pretty easygoing, peaceful person," Motes tweeted before signing off.

Mysteriously all the tweets from Motes' Twitter account have been deleted.

"Nice how someone deleted @dabbs76 tweets after she died! #RIP #nancymotes, " one twitter user commented.

"Quite the scandal RT @lizetteboz: Nice how someone deleted @dabbs76 tweets after she died! #RIP #nancymotes," said another.

Officials are still waiting for confirmation of  cause of death though the suicide letter has pretty much ruled out foul play.

"She's being examined today. We are waiting for the doctor to provide his findings. There were prescription and non-prescription drugs found at the scene. Cannot tell you what those drugs were. The role the drugs may or may not have played is not yet known. The investigator at the scene listed at this point that he is going with suicide and we are waiting for the doctor to finish the examination. We haven't gotten anything yet," Lieutenant Fred Corral of the Los Angeles County Department of Coroner, told Us Weekly in a statement earlier this week.
