John Dean Slagill, also known as Johnnie Dean Slagill, was 32 when he vanished from near Dillingham, Alaska on November 28, 1990. He and his companion Terrance Sam Batchelder left the fishing vessel Red Jacket in a small skiff to go to nearby Seguam Island to collect fresh water and were never seen again.

Slagill was reportedly wearing brown insulated Carhartt bib overalls, a yellow rain suit, an orange life jacket and orange or red fluorescent gloves; Batchelder was similarly dressed for the conditions. The skiff, the men and any sign of what happened after they departed the Red Jacket have never been located. The Alaska State Troopers handled the case.

The circumstances after the skiff left the main vessel remain unknown. Does anyone who worked on the Red Jacket or fished that area in 1990 have memories or information about that trip?
