From the Find Craig Arnold Facebook Group:
5/4 12:19pm EST: Craig's brother Chris, who is on the island of Kuchino-erabu, has communicated that he feels the search is progressing really meticulously and professionally, and that the people of Kuchino-erabu have been passionate about finding Craig, for which they continue to have our most profound gratitude. The search is narrowing and the Fulbright volunteers have been able to contribute to the effort. It rained some yesterday, but the temperatures continue to be good.

I want to iterate that most importantly now, what is needed are two very concrete actions: the donation of funds to the search and rescue operation, and everyone's fervent, immediate prayers that he be found very soon. --jae
