Texas police had accused the estranged wife of world-renowned concert pianist Vadym Kholodenko of murdering their two daughters before stabbing herself.

Police confirmed that 31-year-old Sofya Tsygankova has been charged with two counts of capital murder. She killed her daughters Nika, 5, and Michela, 1. Police said 29-year-old Vadym Kholodenko visited his wife’s home in Benbrook to pick up the girls and discovered the murders. He found his wife in an “extreme state of distress.”  He called emergency services once he saw the carnage.

According to Reuters, Tsygankova injured herself with self-inflicted stab wounds. She was admitted to a Fort Worth hospital for treatment and  would undergo a mental evaluation.  Then she would be sent to Tarrant County Jail in Texas after her mental health evaluation.

Benbrook police Commander David Babcock said, “We have probable cause, reason to believe, that she committed the homicides.”

He also said that police had collected all the physical evidence from the scene.

How the girls died is still shrouded in mystery. The Tarrant County medical examiner’s office informed on Monday that autopsies had not been completed. The police said that the children had no visible trauma.

Kholodenko in a statement said, “The loss of my children will be with me forever. But I would like to say that I feel the support of the Fort Worth community and all people who are sending me messages all over the world.”

He added, “Wherever I go after this tragedy, my heart will stay with the people here of Fort Worth and my daughters will rest in this soil.”

Kholodenko is the winner of prestigious Van Cliburn International Piano Competition in Fort Worth in 2013. He has also performed with the several extremely popular orchestras, reported BBC.

The couple got married in 2010. They migrated to Forth Worth from Moscow in 2014.  But the couple divorced in November last year. The children were staying with their mother.

A mother killing her own children is an unbelievable but rare case.  But last year in December, a California mother microwaved her infant daughter.
