I started looking over folks who went missing in 1984 to give a cushion for runaways who met with sad ends a few years down the line, and allowing for the estimated death date to be slightly off...
here are a few possibilities:
Clifton Patrick Leonard – The Charley Project
16, so at the higher end of the Doe estimation, suffered from schizophrenia
Michael Fischer – The Charley Project
technically too old by either estimation, but went missing from CT and looks much younger, still this one is a big stretch
Christopher James Harvey – The Charley Project
Charley project seems to imply he died on a hike at age 14 in 1984. if he ran away instead and perished a bit earlier than estimated, could be him.
Louis Anthony Mackerley – The Charley Project
classified as a non-family abduction, had previously been approached by a couple, potential assaulted by them.
Sean Wayne Evans – The Charley Project
disappeared from outside his family home when mom ran in to take a call. there was a rive by the house but no body was ever found.
