WESTMINSTER, Colo. (AP) — 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.

At a pre-dawn news conference, police refused to release any details about the body found late Wednesday at a park in the suburban Denver city of Arvada, about seven miles from where Jessica disappeared Oct. 5. They also declined to say whether the body was that of a child.
