Here's a link to an article posted on FR concerning Clinton's alleged coke use in Florida. There had been a picture of a very red-faced Clinton there, but I can't find it now.
All I've been able to turn up on "Barrett Hamilton" is that it's a liquor and beer distributor in Little Rock, AR:
Barrett Hamilton
3801 West 65th Street
Little Rock , AR 72209
ph: (501)565-4641
fx: (501)565-8561

The only specific reference to a dead person turns up here.
