Cajun Navy Relief?
Edited
@JerseyWasHome2 Thx for mentioning this organization.
W a quick online search, I found a website for CNR & a few soc media
accounts.
From what I'm seeing, appears the group focuses more on providing "immediate rescue and relief during natural disasters" than on S & R for missing individuals, like Ryan S.
Just my impression, not a criticism.
I know some S & R groups have sonar & divers who may be be able to help. No names come to mind ATM, but hoping they may join the effort to find him. Some very brave, selfless souls venture out there.
