Adam Gilbertson was last seen in surveillance video in the early morning hours of Dec. 15. He was walking through the parking lot of the old Kmart on South Broadway in the video. Previously it was thought that the last sighting of him was when he left Syntax Physic Opera, located at 554 South Broadway, at approximately 1 a.m. on that same morning.

Denver police have been investigating his disappearance since then and say so far there’s no indication of foul play.

GoFundMe donations have allowed Adam’s family to retain a private investigating team, but they haven’t been able to get any major new leads. Family members have been making trips back and forth from their home state of Minnesota to Colorado in hopes of finding him.

Gilbertson was new to Denver. He moved to the city five months ago to work as a hospice nurse and his mother says he was passionate about helping people.

“It’s been horrible. Adam is not the kind of person who would just disappear. So, everybody is talking about how it’s just not right and how we need to find him because he’s just not that kind of person who would disappear,” said Adam’s sister Amy Linnel. “All the people we’re interviewing around here, in the bars, all say Adam is the most kind person, he would never do this.”

According to the Facebook page Find Adam Ronald Gilbertson, a search party has been planned for Adam on Saturday from 10 a.m. to 4 p.m. Volunteers should meet in the old Kmart parking lot off South Broadway. The search groups will break off from there.
