Rosemary Billquist, 43, was shot and killed while walking her dogs in a field.

— -- A New York woman was shot and killed by a hunter who says he mistook her for a deer, authorities said.

Rosemary Billquist, 43, was walking her dogs in a field in the town of Sherman on Wednesday evening when she was shot by a man about 200 yards away who says he thought he saw a deer, according to the Chautauqua County Sheriff's Office.

The New York State Department of Environmental Conservation Police has joined the ongoing investigation. A preliminary investigation found that Jadlowski fired the shot after sunset, the sheriff's office said. According to New York State regulations, deer hunting is only allowed from sunrise to sunset.

No charges have been filed against Jadlowski at this time, according to the sheriff's office. The Chautauqua County District Attorney's Office will review the case to determine whether Jadlowski will face criminal charges.

The Sherman community held a candlelight vigil for Billquist the day after her death.

According to an obituary for Billquist published Saturday in The Post-Journal, she is survived by her husband, Jamie Billquist, as well as her three brothers. A funeral service is scheduled to be held Wednesday morning.

ABC News has reached out to Billquist's family for comment.
