Academy Award-nominated film editor Sally Menke died Monday allegedly from complications suffered while hiking in the extreme heat in Los Angeles.

According to the Los Angeles Times, Menke, 56, and a hiking buddy set out around 9 a.m. to hike a trail in Bronson Canyon, and an hour later, Menke's partner decided to turn back. Menke and her Labrador retriever continued on. When she did not return home, Menke's friends and family alerted local authorities late that afternoon that she was missing.

Shortly thereafter, a search party was sent out that included dogs, an LAPD helicopter and officers from patrol units, who spent hours in Griffith Park searching for her.

Menke's body was found just after 2 a.m. Tuesday (September 28) at the bottom of a ravine near the 5600 block of Green Oak Drive in Bronson Canyon. According to the Los Angeles Police Department, her dog was sitting next to her body, which was about a football field's length from nearby homes.

The cause of death has not been reported, although sources familiar with the investigation told the Times they believe Menke became disoriented and collapsed and the weather conditions contributed to her death.

Menke was a longtime friend and editor for Quentin Tarantino, having edited all his films, as well as "All the Pretty Horses" for director/actor Billy Bob Thornton.

Tarantino, who was scheduled for a roast at the Friars Club on Friday, has reportedly canceled the event due to Menke's death.
