Investigators in the case of a British family found dead on a US hiking trail are hoping their dog's autopsy could provide answers about their mysterious deaths.
An investigation was launched after the bodies of Jonathan Gerrish, 45, his wife Ellen Chung, 31, and daughter Muji, one, were found in the remote Sierra National Forest, California.
The family dog was also discovered dead.
Autopsies failed to determine how the family died, but investigators are hoping toxicology reports for the family as well as their dog could provide some answers.
Mariposa County Sheriff's spokeswoman Kristie Mitchell told Fox News: "Now that we're five days in, no, we're no longer considering homicide as a cause of death."
She added: "We're hoping that within the next week, two weeks, we'll have a better idea.
"There's toxicology that we're waiting for from the autopsies themselves, and then also from the [necropsy for the dog]."
Last week Mariposa County Sheriff Jeremy Briese told The Mirror: "I've been here for 20 years, and I've never seen a death-related case like this.
"There's no obvious indicators of how it occurred.
Mr Gerrish had recently moved to the area from San Francisco hoping to raise their daughter in "a quiet, slow-paced environment, surrounded by open-air and close to the mountains for hiking and camping adventures".
The family were able to move as he was allowed to work from home due to the pandemic.
The Brit's trip out on Sunday was supposed to be just a day hike.
However, when their nanny arrived at their home to look after Miju, no one answered the door, causing friends to become worried.
Following the discovery of the bodies, police originally began treating the scene as a "hazmat situation" as investigators could not rule out carbon monoxide emitted from old mines as the cause of death.
But Sherriff Briese said they could not find any disused shafts in the vicinity.
