It turned out that the last time the signal from Sergei Usoltsev's phone was detected was in the area of the Kuturchin-Mina highway, not far from a busy village. In addition, there is reason to believe that this family has never climbed a mountain.

Let us remind you that in the Krasnoyarsk Territory they are looking for a couple with a five-year-old daughter in her second week. The tourists are planning a short vacation – according to relatives and friends, as well as comments from Irina herself, they will climb the mountains, admire the picturesque views and return to the entertainment center. The entire route takes about four hours.
In the complex case, two points emerge that are currently being actively discussed. Previously, there was information that at 10:30 p.m. on September 28, the signal from the family's SIM card was recorded.
Rescuers examined the cave where the Usoltsev family, who disappeared in the taiga, could have taken refuge
The head of the Krasnoyarsk search team “Search for missing children named after Oksana Vasilishina” clarifies Svetlana Torgashina aif.ruthat it was recorded in an area with a well-maintained road. Two kilometers from Mina village, this is a bustling place with a population of more than half a thousand people. That is, not in the remote taiga as previously reported.
Of course, this does not mean that the family is the source of the signal. It is not true that the phone was in the hands of Sergei or Irina. Perhaps someone took possession of the family's device. Let us remind you that a criminal case has been opened and investigators of the Krasnoyarsk Investigative Committee are currently working at the scene of the family's disappearance.
The second point is before Usoltsevs, about 20 minutes earlier, another group of tourists entered the path. They noticed a couple with a child at the beginning of their journey, but when they returned from the mountains they no longer saw the family. Do they remember each other, or has the Usoltsev family never been to the mountains? Investigators will have to find out.
One local resident said she saw a family with a baby girl wearing light clothing – but just as they were preparing to go up the mountain.
By the way, law enforcement officers – police and investigators, as well as employees of the Ministry of Emergencies – are now living in Mina, in the village near where the Usoltsevs' cell phone signals were recorded.
