I checked onward and found 2 leads:
1) He may have also been a contributor to Swashbuckling Adventures, an 2002 AEG D20 book. Sent them a note via their FB page.
2) and he may be a registered voter in Ohio:
KEVIN GENE HOSMER CASEY
was born in 1967 and registered to vote, giving the residential address 190 LONGVIEW HTS RD , , ATHENS, OHIO 45701 U.S.A.
