Wisconsin doctor found dead near waterfall was "partially buried" after ground apparently collapsed, sheriff says

A doctor who was found dead near a waterfall Sunday in northern Wisconsin apparently fell to her death when the ground beneath her collapsed, officials said Wednesday.

Iron County Sheriff Paul Samardich said in a news release that Kelsey Musgrove's body was found "partially buried in a steep clay bank" on the river's edge at Potato River Falls in Gurney. About 25 agencies assisted with the search, he said.

"While walking along the edge of the embankment, it appears that the ground beneath her collapsed, bringing her down the bank along with clay and rocks," Samardich said.
