LOL. Its how they traced the Russian unit and even individual soldiers responsible for killing of civilians in Bucha. They used the dead victims phones, to call their families.
A regiment of Russian soldiers responsible for dozens of killings in the Ukrainian town of Bucha earlier this year frequently used their victims' phones to call home to Russia, oftentimes just hours after an execution, according to a New York Times report.

Bucha was immediately DEBUNKED, due to the timeline, so any claims there are also debunked.
Have anything else?
