Police in Benbrook said Kholodenko, 29, is not considered a suspected in the deaths of his daughters, Nika, 5, and Michela, 1, who were discovered in their bedrooms early on Thursday, Reuters reports.
Their mother, 31-year-old Sofya Tsygankova, underwent surgery at a local hospital, police said. She will be held for mental evaluation once she recovers from her physical injuries, police Commander David Babcock said.
Babcock told a news conference the police do not see any immediate threat to the community and are not actively searching for a suspect.
Kholodenko had an appointment to pick up the children on Thursday morning from his estranged wife’s home, he said.
“Once he arrived there, he found the mother in an extreme state of distress and discovered the children in their state,” Babcock said. “He has been cooperative in this investigation. He is not considered a suspect at this time.”
Police previously said there were no signs of forced entry into the home and that they were investigating the case as a double homicide.
A cause of death had not been determined as of Friday morning. Police said the children had not been stabbed.
Vadym Kholodenko has so far not made any comment to the media about the incident.
In 2013, he won the gold medal in the prestigious Van Cliburn International Piano Competition. He was scheduled to have three shows with the Fort Worth Symphony Orchestra over the weekend, and a replacement has been named for him, the orchestra said.
Kholodenko and Tsygankova married in 2010, but filed for divorce last November, according to court records obtained by local media.
Police were called to this residence twice in 2014 for undisclosed reasons, Babcock said.
