Munich, Germany (CNN) -- A story focused on the care of prison inmates with dementia in U.S. jails has scooped two top prizes at the CNN Journalist Awards ceremony in Munich.

Claas Relotius was named CNN Journalist of the Year for the story "Murderers as Carers." The story, first published in Swiss magazine Reportagen, also won the Print category award on Thursday night.

According to Relotius' report, many U.S. prisons are struggling to provide care for long-term inmates suffering from dementia. But one high-security facility has found an unconventional solution to the problem -- by teaching its own inmates to become carers.

"The report takes a poetic and interesting approach to a major social problem. Claas Relotius paints pictures in the reader's mind that unfold like a film,' said Franz Fischlin, chairman of the judging panel.

Meanwhile, Michael Strompen and Jo Schuck's "Escape to the Caribbean -- Corporate Tax Tricks," in which they conducted an in-depth international investigation into corporate tax evasion through shell companies, won the best TV category. Jurors noted how the duo from ZDF succeeded in powerfully "explaining the many numbers, pieces of information and complicated economic interrelations."

The Online category honors went to Christian Werner for "On the Trail of Dead Children." Presented on the Der Spiegel iPad app, he revealed the impact of the bombing of Iraq in 2003 on the health of children.

Also recognized was Jenny Marrenback, who won the accolade of best Radio piece. Her report, "Haiti Cherie. The Business of Aid," explored the aftermath of environmental devastation in Haiti for survivors. Judges praised Marrenbach's work for showcasing "the other side of the coin in the NGO business."

First appearing in emerge, an online magazine for young photojournalists, Birte Kaufmann's series of photographs chronicling the everyday lives of Ireland's traveler community, won top honors in the Photo category. "Birte Kaufmann provides an intimite and deep insight into a totally foreign world," said the awards panel.

Parisa Khosravi, senior vice president for CNN Worldwide said: "CNN continues to do its part to support quality journalism by sharing our experience with journalism colleagues around the world through a number of different programs, such as the CNN Journalist Award, now in its ninth year.

"It's so heartening to see strong journalism thrive and grow through such competitions and we're delighted to support this initiative for German-speaking journalists."
