The failed rescue of 'Emma'

Found miraculously alive under the rubble Wednesday, rescue workers toiled delicately for hours to pull her out. But an aftershock made the team leave and when they returned for one more effort Thursday morning, Emma was dead.

The Turkish and British rescue workers in Muzaffarabad, the earthquake-ravaged capital of Pakistani Kashmir, run the series of events over and over again in their heads.

Distraught, they wrestle with questions about guilt, duty and danger and wonder what they could have done differently.

But, they repeat to themselves, they had no choice. At 1:24 am Thursday, a new earthquake of 5.6 on the Richter scale left the collapsed house too dangerous to work on.
