How easy is it to fake human ashes?

Sandy's ashes or sandy "ashes". How easy is it to fake human ashes? Take a walk along the beach and you'll find lots of material to make fake cremains. A mixture of sand of other substances could be passed off as cremains.




According to Tom Bodkin, a forensic anthropologist with the Hamilton County Medical Examiner’s Office: "Those cremated remains could contain any fine powdery material like wood ash, cement, sand, soil, or concrete powder rather than actual cremains. All have a similar texture." So after Sandra is incinerated, will the urn contain Sandy or just be sandy?
