Ronald Stephen Bartel, a 50-year-old student at Kauai Community College, disappeared from his Lihue, Hawaii, home and was last seen by a neighbor on the morning of Sunday, April 5, 2015. College staff reported him missing that day after he didn’t attend classes and an official report was filed with the Kauai Police Department.

Bartel is described as a Caucasian male, six feet five inches tall, about 250 pounds, bald with blue eyes, and has a tattoo of an unknown design on his right calf. He was last reported wearing a white t-shirt and shorts. A green 1997 Nissan Quest minivan is associated with him, but it is not publicly known whether the vehicle was missing.

There has been no contact with family or friends since he was last seen, and the case has produced no significant leads. If anyone knew Ronald, his routines, or saw him or his vehicle around Lihue on or after April 5, 2015, please come forward with information.
