KALAMAZOO, MI -- A 50-year-old woman, knocked off her feet by a 5-year-old's hug, stumbled through a second story window with the child, both falling to the ground 15 feet below, authorities said.

Lt. David Boysen of Kalamazoo Public Safety said both were conscious and alert when public safety officers arrived on the scene shortly after 11:15 a.m. Tuesday. They were taken to Borgess Medical Center, where their conditions were not immediately known.

Boysen said at 12:20 that officers were still on the scene of the accident, in the 900 block of Rose Street, and he was not sure of the relationship between the woman and the child, nor if they lived in the building where the accident happened.

The preliminary information was that "they were on the stairs, the kid ran up and jumped to give her a hug, and the momentum carried them through the window," Boysen said.
