Julia Roberts has pulled out of a series of awards season appearances following the death of her half-sister.

Nancy Motes was found dead from an apparent drug overdose in Los Angeles on Sunday (09Feb14), and the sad news prompted the actress to pull out of Academy Awards' Nominees Luncheon in Beverly Hills on Monday (10Feb14), and a scheduled appearance on late-night show Jimmy Kimmel Live!

Reports suggest the production assistant's body was found in a bathtub, with prescription and non-prescription drugs found on the scene.

Los Angeles County Coroner representative Lieutenant Fred Corralis released a new statement about the death on Monday.

It reads: "Nancy Motes was found dead at a residence in the bathroom yesterday, pronounced dead by the LA Fire Department at 2:12pm yesterday. Not sure whose residence it was. She was found in a bathtub that had water in it. We're taking it as a suicide, not a drowning. 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."
