If anyone has any tips, on Dave or scuttlebutt in the Burney Ca., Congregation Shasta County investigators would appreciate a call. http://www.co.shasta.ca.us/index/sheriff_index/divisions/major_crimes.aspx
Burney is a remote congregation in the mountains that is more insular than most. I heard rumor of a child molestation situation there. If Dave had a position in the Congregation, he would have been a convenient target working at the counter in that remote Johnson Park Gas Station outside of tiny Burney. The old P.O. Don Garloff, was harsh and famous for jockeying for "circuit/district priveledges " and at the forefront of WTBTS dark side shell games with Assembly Hall finances, Theocratic Strategy, etc.
I didn't know him personally, but Dave seems to have been well-liked in the community. In his pre-JW days, he was a musician in some Metal bands albums. Bassist of RazorMaid, Boss Hogg, and Izzy Ozborne in the 80s.
A Go Fund Me page exists for his burial and widow. https://www.gofundme.com/david-wicks-family-support-fund
