The estranged wife of internationally renowned pianist Vadym Kholodenko has been charged by police in the U.S. state of Texas of killing her two young daughters before stabbing herself.
Sofya Tsygankova was charged on March 21 with two counts of murder in the deaths of 5-year-old Nika Kholodenko and 1-year-old Michela Kholodenko.
Police say the girls were found dead in their beds in a suburb of Fort Worth, Texas, on March 18 and that Tsygankova was found in an "extreme state of distress."
Police aid Tsygankova -- who is a pianist from Russia -- is in a Fort Worth hospital where she is undergoing a mental health evaluation.
The Ukranian-born Kholodenko won the prestigious Van Cliburn International Piano Competition in Fort Worth in 2013, beating about 30 finalists from 12 countries for the prize.
Kholodenko and Tsygankova married in 2010 and filed for divorce in November.
They had been living in the United States since 2014.
Kholodenko was not living with Tsygankova and their daughters at the time of their death but had reportedly been picking the young girls up each morning.
