Okay, I looked back at the recent DailyMail article where it says:
"According to forensic anthropologist Arpad Vass, PhD, a pioneer in chemical analysis of human decomposition, those samples are 'consistent' with Steve Hodel's theory of homicide victims buried in shallow graves 70-80 years ago.
'The soil came up positive for human remains because there are a number of human specific markers,' said Vass from his laboratory in Oak Ridge, Tennessee.
Hodel would like to search further for the human remains, but has been unable to get permission to go onto the privately owned hillside."

So, its soil, not bones. Its an interesting concept. Is it ground up bones in the soil, or just a smell? I don't quite get if the soil is from the unfinished basement of the house, aren't there other types of instruments that can look for buried bones without digging? I don't think I would want Hodel digging up the basement of my house.
I still think Hodel is crazy. When I have extra time and inspiration, I will look to see if I can find out if the house was built on some burial grounds of some sort.
