I'm not sure why there are so many more people who live upcountry that have gone missing but with the sparse population, rough terrain, dense foliage and ocean, I can understand why they are less likely not to be found. I did check Namus for unidentified bodies on Maui as well. I did not find any records listed so Maui PD must not be entering the unidentified people cases in the national database yet. I believe they just started entering the missing people in Namus recently. The homeless population is a hard one for all communities to manage. Many have mental health and substance abuse issues. Many have lost contact with family and when they pass away, they often do not have id and are known by only nicknames or first names. If the homeless don't have finger prints in a national database or if they are too decomposed to obtain finger prints, it is hard for the coroner to find their names. The good news is that with Social Media, many of these lost souls are being identified by scores of volunteers that work to identify them. Hopefully, Maui will start entering these unidentified people in Namus so these volunteers can go to work.
