This electric torch was first carried by Eugene Odegard when he was going up the circular tunnel. It was later appropriated for the use of Evgeny, Traicho, and Elena. Elena carried it inside her jacket/floatation device when having to swim through water.
Another flashlight was used to illuminate the tunnel beyond where Traicho and Evgeny had parked their car after going down the alley and underground tunnel that leads to the oriental house.
