Looking at Namus, this Indiana MP Sargent Micek was just added on April 28, 2015. Although he was last seen in 1989, he apparently picked up a couple of DUI charges in 1993. Height in range, has light/medium brown hair, but he would be a little older than the UID's estimated age in 1995. He disappeared from a South Bend bar at 3am after his mother told him to call a cab and refused to come get him. Remember the UID was yelling about a woman.
Here is his link: https://www.findthemissing.org/en/cases/28485/6/
Dentals and DNA are both "not available", his FP are on file "elsewhere". But since the UID was 98% skeletal, FP are not going to help much.
