CONSTANTIA, N.Y. -- Oswego County's sheriff and district attorney continue to withhold the name of the man a deputy shot and killed Friday afternoon.

Deputies were called to a house on Auringer Road, a secluded dead-end road off County Route 23 in the town of Constantia. According to a news release, a deputy was responding to a check-the-welfare call and at some point a 58-year-old man was fatally shot.

The sheriff's office has not identified the man killed or the deputy involved and has not provided an account of events.

District Attorney Greg Oakes.

Sheriff Reuel Todd has not returned phone messages seeking comment. District Attorney Greg Oakes has declined to identify the 58-year-old man or discuss the shooting.

On the third day of an information blackout, the only disclosure was from a spokesman for the New York State Police, which is assisting with but not leading the investigation.

At least 15 state troopers are assisting in the investigation at the request of Todd and Oakes, Trooper Jack Keller said Sunday in an email. Only one sheriff's deputy shot the 58-year-old and evidence is being gathered for a possible grand jury investigation, Keller said.

Some district attorneys, by policy, present the case to a grand jury if a law enforcement officer kills a citizen.

Keller said the shooting occurred at 168 Auringer Road.

County property records list 58-year-old David Schwalm as the owner of a 3-bedroom ranch house at 168 Auringer Road. Voter registration records also list Schwalm as living at that address. No one answered a phone number listed for Schwalm on Sunday.

Oakes said an autopsy was scheduled for Sunday.

It's not unusual to for police to wait several days before identifying an officer who shoots a suspect.

But in several recent Central New York cases, police have identified the people shot by officers in days or even hours.

Last fall authorities in Utica identified an officer and suspect the same day the officer chased and shot the armed suspect. Auburn police took a single day last year to name the estranged husband who broke into his wife's home and attacked officers with a meat cleaver before being fatally shot.

In 2013 Onondaga County's sheriff identified a former corrections officer as the armed man deputies had shot and killed the night before. In 2011 Syracuse police identified a suspect the same day he was killed by an officer.
