I would suspect it was a Bald Eagle attack, especially if it was a daytime event. There is lots of documentation of eagles taking young ospreys from nests. Easy, low risk meal for the eagle, as well as reducing competition from a predators point of view. Unfortunately, they often continue returning until the nest is empty. Hopefully the remaining chick will fledge before the eagle returns.

One of the adult Cedar Rapids Ospreys has died in the nest, lying on its side with one wing extended in a grotesque posture. One adult visits the nest periodically and there is one chick, nearly ready to fledge. I cannot confirm the presence of its 2 siblings.
A non-birder neighbor saw a "violent fight" at the nest a couple of days ago. Was this a territorial dispute or an attack by another raptor? Great-horned Owl comes to mind, although the altercation was in daylight on one of those inhumanely hot days.
At best, obviously, we can hope for one successful fledging this year and perhaps
our surviving adult will return next year with
a new mate.
This is at the cell tower at Wenig/J Ave. in
NE Cedar Rapids.
