We do not know they were false alerts in this case.
As has been well established, the forensics were inconclusive.

What was inconclusive in the apartment? You and I probably share 5 alleles or more in common with her. It means nothing. If you check the DNA results, you'll find that unrelated people did.
The other aspect is how many VOCs would have been present in any significant amount that could be excluded from a random mixture of isolated molecules present in everyday life, if she had died there for any reason, that would still have been there 3 months later, bearing in mind the limited time between alleged death and removal.
That might be plausible if she had died there and her body had been stuffed in an underground area of some kind beneath the apartment. I'm not aware of any underground cellar, nor what the sewage system actually was, nor whether there was any access to it.
