Story highlights Man says he fired one shot from about 200 yards, police say

Husband says his wife loved her labs, would do anything for anybody

(CNN) A woman walking her dogs near her western New York home was fatally shot Wednesday by a man who told police he mistook her for a deer.

Rosemary Billquist, 43, was hit by a bullet from a single-shot pistol fired by neighbor Thomas B. Jadlowski, said Sgt. Josh Ostrander of the Chautauqua County Sheriff's Office.

Jadlowski told investigators he was 200 yards from the victim when he fired.

When Jadlowski realized his grave mistake, he called 911.
