Law enforcement officials have confirmed that James Kim has died.
Friends of the family have set up an unofficial PayPal donation page, though they warn you that they haven't talked to the Kim family about it yet. The thought is that the family can decide where to send the money after it's collected. It looks like you have to go through their page to make the donation, so if the page is busy, keep trying to get through. [Thanks for the info, Tiffany!]
CNET is also accepting gifts and donations on behalf of the Kim daughters. Send to:

We're still trying to figure out how you can give money to Josephine County, Oregon, or the rescue volunteer who was injured yesterday. And we'll keep you updated on other ways you can show your support as we find out.
