A woman offers prayers during a candlelight vigil for the missing passengers of a sunken ferry at Danwon High School in Ansan, South Korea, Thursday, April 17, 2014. An immediate evacuation order was not issued for the ferry that sank off South Korea's southern coast, likely with scores of people trapped inside, because officers on the bridge were trying to stabilize the vessel after it started to list amid confusion and chaos, a crew member said Thursday.
