An investigation begins after a corpse is found inside an elevator.
The discovery of a woman's corpse in an elevator in the Chinese city of Xi'an has led to the detention of an elevator maintenance crew who improperly cut off power to the elevator a month ago without checking if anyone was inside.
In a statement, the Gaoling district government said two maintenance workers turned off the power on Jan. 30 after they were called to check on a glitch.
A repair crew returning a month later found a female corpse.
