Update:
Cause of death for the humans is hyperthermia and probable dehydration; for the dog is undetermined but heat related.

Wondering if the infant was first to show problems of heat stress and the parents tried to get out of there. No mobile coverage. Should have had a PLB.

That dayhike was doomed from the start now that we have more info on their gear/provisions. Yes, the child was probably most vulnerable followed not far behind by the dog, imo.

The dog cause of death being undetermined may be the result of knowing that anatoxin-a can kill animals and Oski was too decomposed to properly rule it out.

It is so tragic to see a group of 4 die this way that, in two months, I never saw one mention (over multiple websites) of that certain award given to those who make this type of mistake and don't make it.

In that cause of death announcement it didn't really sound like they gathered more info than they already had. It was more like they threw up their hands and guessed heat.

109 degrees that day.

With 35 assisting agencies to rule out a multitude of violent and nonviolent causes over two months in a group death in extreme weather where no obvious signs of foul play are seen, this case was probably one of the most thoroughly investigated deaths in my lifetime....that is hardly throwing their hands up.

Because of the circumstances, it was always going to be heat-related until proven otherwise, and 35 assisting agencies could not prove otherwise.

Final Update on Gerrish / Chung Family

After multiple months with the FBI computer/phone forensic team, the Mariposa County Sheriff’s Office has obtained details from Jonathan Gerrish’s phone.

In October of 2021 we released the cause of death determined by the Pathologist. This was based on autopsy results, our investigation, and a multitude of toxicology/scientific test results. The cause of death for Jonathan Gerrish, Ellen Chung and Aurelia “Miju” Chung-Gerrish was determined to be Hyperthermia, and probable dehydration due to, environmental exposure. Hyperthermia- The condition of having a body temperature greatly above normal.

Using the information extracted from the phone we were able to re-create the path and timeline based on the GPS locations. The details found on the phone support the findings of a heat related incident.

“The cell phone data results were the last thing both the family and detectives were waiting on. The extracted information confirms our initial findings. I am very proud of my team and our partner agencies for all the work they put in. Their dedication has allowed us to close this case and answer lingering questions the family had, bringing them a little peace.”- Sheriff Jeremy Briese

Sad. I imagine that even if they had reception for any of those calls, it wouldn't have changed the outcome.

The heat load in Arizona deserts can e unbelievable, especiallu if you are not acclimatized.

Doing a SAR mission in Tucson on a dy when the temp "only"reached 90F, may companion and I ran through 3 1/2 gallons of water, starting about noon, hiking swiftly uphill over 6 miles on a south facing slope, finally reaching a known dependable water source. We were dehydrated and drank deeply. That was an extreme situation, but you get the drift.....
