The wife of a famed concert pianist is being held on a mental health evaluation after he found their two children dead at her home.
Vadym Kholodenko arrived at his estranged wife's home in Benbrook, Texas, to find his children Nika and Michela Kholodenko dead and his wife in a 'distraught state' with multiple knife injuries.
Kholodenko is not a suspect, and Benbrook Police Commander David Babcock said they are not 'actively looking' for anyone in the ongoing investigation.
Although Sofia Tsygankova, 31, is not officially a suspect, it raises the possibility that she murdered her children and then injured herself.
Kholodenko had filed a divorce from Tsygankova in November after the couple arrived to the US from Russia in 2014.
He was educated in Russia and the couple had been living in Moscow while also travelling the world as his fame as a pianist grew. He won the Van Cliburn international piano competition in 2013.
However Ukranian citizen Khodolenko began to be harassed by the Russian authorities when war broke out in his homeland between Russian-separatist forces and the Ukranian government.
They came to the US in 2014 and settled in the Fort Worth area because of Khodolenko’s close ties the city’s symphony orchestra.
But the relationship appears to have soured and Khodolenko filed for divorce in November 2015, and the pair had been living separately since August of that year.
Kholodenko was due to perform this weekend with the Fort Worth Symphony Orchestra, but another pianist will take his place.
