The number of dolphins who have died since being trapped in a shallow creek off eastern Long Island has risen to 10, a rescue leader said.
About 20 of the "common dolphins" were first sighted about 11 days ago in the Northwest Harbor cove, which is north of East Hampton, about 100 miles (160 kilometers) east of New York City. Eight dolphins swam to safety earlier in the week after being coaxed out of the cove, and three were spotted Friday. Officials do not know how many are still alive.
More than 80 people have been involved in the rescue effort. The 10th dolphin's body was found midmorning Saturday, officials said.
