I've been looking through UIDs and I see very few listed as Asian. How likely would it be that skeletal remains, especially pre-1980, are listed as white? I could also see the Asian community being hesitant to get involved with the police given the long proven history of racism in the US. I'm just not sure how easily MEs were able to tell the difference before science got this far.
I have wondered this as someone who is mixed Asian myself, and I also wondered about Christy Crystal Creek (Janet Lee Lucas), who was thought to be an Asian woman (specifically Japanese), but was instead fully white, no traces of Japanese or any other Asian ancestry. I have no idea why they thought she was Japanese in particular.
Estimating race from skeletal remains is just flat out wrong sometimes, because it's not an exact science. There's been cases similar to Janet Lee Lucas's where the race was incorrect. One more well-known one was Princess Blue (Julie Davis) who was white and thought to be black. There is also a woman whose name I unfortunately cannot recall who was depicted as a heavier white woman and was actually a petite black woman - for this lady, they also said she had never given birth, but she had multiple kids, I think 4 or 5. Estimations from skeletal remains can also be pretty off for height, age, etc. since it is so hard to estimate. (Ex: Marilee Bruszer).
One factor that I have wondered about is less of Asian remains being categorized incorrectly as white and more of them actually being categorized incorrectly as Native American. To me, this makes a lot more sense from multiple different perspectives, especially with human history being so that Native Americans were descended from ancient Asian populations, and that there are genetic similarities there. Lots of Native Americans are thought to be Asian by people and vice versa. So, I could see this easily happening.
I have to wonder if part of it is also because lots of UIDs are found dumped in rural areas and there are far larger Asian populations in coastal cities and other urban areas, rather than these areas. Just a thought. There is a large Asian population in the Los Angeles area, and I've seen some UIDs listed as Asian from the area.
