The family was on a hiking trip near Mount Buratinka in Krasnoyarsk Krai.
The family included Usoltsev's wife, their five-year-old daughter Arina, and other children.
A search operation involving over 1,500 people was conducted in the area.
No significant evidence was found until a walking pole fragment was discovered in early summer 2026.
Valentin Degterev, a friend of the family, disclosed information about Usoltsev's secret family and extramarital daughter.
Usoltsev had four children: a daughter named Iryna from his first marriage, a son Mikhail living in the US, an adult extramarital daughter, and a five-year-old daughter named Arina.
The family was traveling in a personal Skoda vehicle.
The family's vehicle was checked and found to lack camping gear.
