CHARLOTTESVILLE, Va. (CBS19 NEWS) -- The Theta Chi fraternity at the University of Virginia is calling on the community for help after a painting was stolen. It's a work of art honoring a fallen brother.

"It was there one day and it was gone the next,” said third-year student and Theta Chi brother Ray Ruhlmann.

Warmbier was a UVA student imprisoned in North Korea while on a guided tour in 2016. He was later released by North Korea in a coma and died soon after.

"A lot of the guys are very upset that they've been stolen. Especially the fourth years who knew the guys who knew Otto,” said Clay Hardy, president of the UVA Theta Chi chapter.

Hardy adds the paintings are a constant reminder of Warmbier's bravery. But they were taken from the Theta Chi house at 600 Preston Place.

"We just want it back. We don't want any repercussions placed upon them for their actions," Hardy said.

Ruhlmann says it's a big house where many members live, which means guests constantly come in and out. So it's hard to say who it could have been.

The brothers say what may have started as an innocent joke will have lasting impacts on the brotherhood at Theta Chi.

"Composites are very commonly taken from fraternity houses. The problem with that is, this is not a composite. This is something that is a lot more special to our chapter,” said Ruhlmann.

The paintings have been gone now for two weeks, disappearing around the evening of Sept. 22. But the brothers didn’t notice they were missing until the following day.

"I don't think there's any real reason why someone stole this, which is the most upsetting,” Ruhlmann added.

Chapter Vice President Georgi Solar says alumni who knew Warmbier will be back next week for a reunion and says the current brothers would really like to have it back before then.

"It's disappointing we won't have that memory up in the house for them,” Solar adds.

The brothers say if you have the images, please just leave them on the front porch, no questions asked.

If you have any information on the paintings’ whereabouts, please contact the Charlottesville Police Department at (434) 970-3280.
