An eastern Nebraska man has been found guilty of child abuse resulting in the death of his infant daughter.

Attorney General Jon Bruning says 31-year-old Ryan Kozisek, of Gresham, was convicted by a York County jury on Friday for the death of his 4-month-old daughter, Kayley Kozisek. Kayley died at an Omaha hospital on Jan. 25, 2011, a day after Kozisek called 911 and said she wasn't breathing.

Kozisek told emergency crews that his 2-year-old daughter accidentally fell off a stepping stool and onto the baby. A doctor told investigators the baby's multiple injuries -- including severe hemorrhaging and brain trauma -- could not have been caused by a 2-year-old.
