These chemicals were used in a "suicide wave" in Japan and the US: Web Link

While I am certainly no expert about recreational drugs, I was under the impression that the "rotten egg" smell was often associated with meth production. A quick Internet search led me to this article:

Web Link

If my assumption is correct, nearby residents were probably evacuated because meth labs use flammable chemicals for the drug production and the police were worried about a possible explosion/fire.

The fact that the MVPD have released very little information indicates that this was not a simple accident nor utility issue. It is likely divulging too much information at this point might jeopardize their (criminal) investigation as they interview neighbors, etc. about the occupants' behavior, research vehicle movements, etc.

Again, this is a guess.

@parent:

I did poke around various articles about the "weapon of mass destruction" angle and this scenario seems less likely.

For starters, a WMD is more effective if it is very large/quick (like a suitcase nuke), or if it is very undetectable (like sarin nerve gas which is odorless). The noxious smell the apartment was emanating would not make an effective WMD as people would tend to back off.

Second, a WMD operation would most certainly mobilize the feds, and right now this appears to be a municipal police case.

Moreover, the justification of a homemade WMD is relatively marginal. Unlike drug production, there's little financial benefit from building something that essentially returns no revenue.

Again, I am no expert on the WMD topic, but the fact that the feds haven't overrun Mountain View is pretty good evidence that this is not a WMD factory.

As posted on MVPD's facebook page (not by them) it sounds like detergent suicide chemicals. Although that is pretty elaborate for someone living in an apartment on that block IMO. Although...one of the detergent suicides in Japan was a 14 year old

Yes, it could be a detergent suicide although it would be one of a handful here in this country. Detergent suicides don't appear to be an upward trend here in California or elsewhere in the United States. It is worth noting that some chemicals could be used either in a detergent suicide or in drug manufacturing.

Let's face it: there are plenty of other ways to end your life around here, many of which are much more "easier" whether it be a firearm, hanging, prescription drug overdose, on the train tracks, or jumping off a bridge.

Detergent suicides are probably more common in Japan since the general populace there does not have access to handguns: firearm ownership by a Japanese citizen is illegal and importation is also forbidden.

Again, the extremely limited amount of information provided by the MVPD would seem to indicate that they are working on a criminal investigation. If this was a detergent suicide, there would like be nothing else noteworthy inside the apartment unit.

However, if it were indeed some sort of drug lab, there would be a lot of evidence that the police would need to examine, inventory, investigate, etc., all of which would require some time, and explain the extremely cagey communications by the MVPD.

Should wait until the investigation is completed before further speculating. The article stated that the chemicals were found at the complex, not inside the apartment.

Yes, far too much speculation in comments on the case so far. Wait for the full story.

Today's Daily Post has other details. Including from an apartment resident (manager?) Daryl Smithgall, quoting the Fire Chief as saying that a note found on the Lius' apartment door referred to using chemicals inside the apartment that might create a small. It sounds like the same note CBS et al. persisted in labeling in news broadcasts as a "suicide note," even long after MVPD spokeswoman Tanaka was reported here saying "We are investigating something that was left, but it was not a suicide note." 

Hydrogen sulfide gas smells really bad, but it quickly overloads your sense of smell. Then you can't smell it anymore even though it is deadly in high concentrations. Very sad situation.

Hydrogen Sulfide is what you get when you break those tiny stink bomb vials.

Its like rotten eggs x100. Really bad. You used to see them all over in SF Chinatown.

Just a correction point, there is no "apartment manager" on site, this is not an apartment complex but a condominium building with an HOA board.

Thanks David.

The ambiguity was in the current (weekend, print) Daily Post, which describes Smithgall as another "apartment complex resident. . . who is also the president of the homeowners association."

As a frequent customer of the Milk Pail, this makes the story even more sad as I probably had been served by him.

Condolences to the family and all Milk Pail employees.

Hello Jay Park,

The number of detergent suicides in the US is certainly higher than just a handfull. In my register I have 21 in California alone, and my register is far from complete.
If anyone needs more accurate info, he or she should contact mr. J. Oreshan,
Deputy Chief with the New York State Office of Fire Prevention & Control. He has specialised in this subject and keeps a register of US victims

updated: Suicide and accidental death.

Web Link

From the police blog:
"While we are continuing to investigate this case, at this point in time the deaths of our two victims appear to be the result of a suicide along with one accidental death. One of the victims has been identified as 53 year-old Lian Liu, a male out of Mountain View, however we are not releasing any information about the other victim who is a juvenile. We ask that you please respect the privacy of the those involved in this extremely unfortunate incident and offer your continued support to those in our community."

I'm assuming one person was trying to resuscitate/save the other and died in the process. So very, terribly, sad.

Well, I'm just sad about this story.
Even though I'm not a Milk Pail regular, I do know its excellent reputation for wonderful fresh products and lovely staff.
So I'm sad to hear about the suicide or accidental death of the manager and his son... story is unclear about which victim was suicide or accidental.
AND I REFUSE TO DIMINISH THESE LOST PEOPLE WITH SPECULATION..and I do wish other commentors here would do the same. Too much speculation here.

I agree with the comments of Baxman, Max Hauser and Casey. Some restraint is needed to be respectful of this situation.

"While I am certainly no expert.."

So why concoct a story about it?
