Linda Williams Notes: The list was primarily an on-line search through area media, and only includes missing people that did not result in either the person or their remains being located within a short time after going missing. It also includes cases where remains were found and never identified or identified months or years after the missing report was filed. The list does not include missing person’s reports filed in other jurisdictions where the last known location was in Mendocino or Humboldt counties.

    The Donald Cavanaugh (missing May 2005) & David Neily (missing May 2006) cases both make the hair on the back of my neck stand up. There is too much coincidence surrounding this man James (also known as Jim &/or Jimmy) DeNoyer & his involvement with both men.
    Why have they not dug deeper into things?
    Why was Neily’s son not called to witness or interviewed for a legal statement when James was on trial for something like 36 counts of animal abuse & neglect against his horses?
    Too many coincidences in these too cases & their obvious involvement with this man.
    When will someone dig deeper??? There needs to justice & closure for the families in these cases!

    Good questions Christina & Thank You!
    The first horse abuse trial they sent an subpoena for my brother to my dad’s address in Albion, October 10, 2006. Ryan was not living there. The Sheriffs had his current info. The second trial my brother sent a notarized statement dated March 24th, 2008 to Katherine Houston, Deputy District Attorney with all updated contact info. He was never called.

    We can not afford a lawyer, PI or reward money. We are stuck!
