Found Deceased NAMUS Missing persons still listed after being found

[ForsakenRoses]

Recently I've started tracking and researching cases on NAMUS and assumed that the site is kept well maintained. However out of the 19 recent cases I am tracking, I have read reports that the following 2 females have been found deceased although their NAMUS cases are still up:
~Tammy Harris
~Sharon West
Is it up to Law Enforcement to close a case on the site? Sharon's body was apparently found in 2 months ago.
