The estranged wife of renowned Ukrainian pianist Vadym Kholodenko sought mental treatment the day before she allegedly killed their two daughters in their Texas home, police said on March 22.
Sofya Tsygankova is accused of capital murder in the deaths of 5-year-old Nika Kholodenko and 1-year-old Michela Kholodenko.
Vadym Kholodenko found the two girls dead on March 17, with Tsygankova wearing a blood-stained nightgown and kneeling on the floor "rocking back and forth," according to the arrest warrant. She had wounds on her wrist and chest, and a butcher knife was found nearby.
An empty bottle labeled with the antipsychotic drug Quetiapine was found on the kitchen counter, police said.
Authorities said Tsygankova, who is divorcing Kholodenko, visited a mental health facility the day before the murders.
Tsygankova told police she remembered putting her children to sleep and taking pills, and believed she hurt herself with a knife. But she asked the officers if she had done "anything bad" to the girls.
Tsygankova was booked on March 22 into the Tarrant County jail.
