Russian-born Eugen Martens, 45, told RFE/RL in January that he had applied for repatriation under a Russian government program in October and settled with his family in Kyshtovka, a village in the Novosibirsk Oblast, in December.
Martens and his wife, Louisa, were born in Siberia's Omsk Oblast and were among hundreds of thousands of ethnic Germans who emigrated from the former Soviet Union to Germany in the 1990s.

Russian media reports on February 27 quoted a friend of the family in Kyshtovka as saying that they had left for Germany on February 24, flying out of Novosibirsk.
Local authorities said the house given to the family in Kyshtovka has been empty for days.
The reports did not indicate why they decided to go back to Germany.
