WESTMINSTER, Colo. – Colorado police looking for a 10-year-old girl who disappeared on her walk to school have found a body in a park, but are not saying whether it is linked to the case and noted Thursday that officers are still searching for her.

The discovery of the body is the latest turn in the disappearance of Jessica Ridgeway that has seen police look for clues in a reported sighting in a car with Colorado plates in Maine and a Wyoming abduction. The FBI said Thursday that abduction was unrelated.

Police spokesman Trevor Materasso said the body "is not intact," and that has slowed the work of identification. Materasso said no other information would be released until Friday, and he left a brief midday news conference without answering any questions.
