Could it be that the Osulzabs sent a signal from their cell phone?
The Osultsev family - Sergey, Irina and five-year-old Irina - disappeared in the taiga of the Krasnoyarsk Territory in September of last year. They went for a walk to Pinocchio Rock with one mobile phone between them and never came back. IT expert Elder Mortzin explained to AiF whether the missing can send an SOS signal.
"Where there is no connection, you can send an SOS signal only through a satellite, if such a satellite exists. It doesn't work in Russia. Therefore, they could not get a connection and could not send a signal from the phone. Without communication, a telephone is a useless thing. If they find this phone later, they will probably find a record of recent actions there," the expert said.
He also noted that the Osultsevs' cell phone may still be working, even after being exposed to rain and snow for several months.
