A report stated that authorities have closed down campsites and hiking trails in Yosemite National Park after discovering the mysterious deaths of a family member and their dog.
The bodies of the British family Jonathan Gerrish and Ellen Chung, along with their 1-year-old daughter Miju, and Oski, the family dog, were discovered in remote areas of the Sierra National Park, near the Savage Lundy Trail, on August 17.
The cause of the deaths remains a mystery to detectives.
According to the Sierra National Forest, the area where the bodies of the family were discovered was closed as a precautionary measure due to “unknown dangers found around and in the Savage Lundy Trail“.
The national forest stated in a statement that “designated recreation sites, roads and trails in vicinity and/or leading there will be off-limits for the public.”
The affected areas will remain closed through September 26.
Initial autopsies of the family members and necropsy of the dog did not reveal what caused their deaths. Toxicology results are still pending.
Although police have been able to rule gunshots and other weapons out of the Savage Lundy Trail, it is possible that there are still potential toxins.
Water samples from the region were sent to be tested, along with the water that the family had packed.
The FBI is now extracting data from phones belonging to the family after searching the home and car of the family.
After the discovery of the bodies cops couldn’t initially rule out carbon monoxide from old mines being the cause.
Sherriff Briese stated that detectives could not find any abandoned shafts in the vicinity.
He stated, “We haven’t found any old mine shafts in the vicinity.”
“There are some mine shafts, but we don’t know if they’re the cause.”
