Sculptor Patrick Farrow, 66, was found late Monday by police responding to an emergency call from the Farrow Gallery in Castleton, a small town near the New York border. A woman there had called asking for help.
An autopsy was planned to determine the cause of Farrow's death. Police said they wouldn't release additional information until it was complete.
State police Lt. Timothy Oliver called Farrow's death suspicious in a written statement Tuesday. Oliver, who didn't respond to telephone calls on the case, told WPTZ-TV that police don't suspect foul play, but he said there were some things out of the ordinary at the scene; he didn't elaborate.
Farrow, a professional sculptor for more than 35 years, operated out of a converted church building. The Farrow Gallery sells jewelry and mixed-media works of art, according to its Web site. The gallery is owned and operated by Farrow and his wife, artist Susan Farrow.
Mia Farrow, whose movies include "Rosemary's Baby," "Hannah and Her Sisters" and "Crimes and Misdemeanors," is the former longtime companion of director Woody Allen.

Farrow is the daughter of director John Farrow and actress Maureen O'Sullivan.
David Schilling, an assistant to Mia Farrow's manager, Laura Berwick, said late Tuesday he had just heard of Patrick Farrow's death. He had no immediate comment on it.

Sgt. 1st Class Jason F. Dene, 37, died of injuries suffered in an incident in Baghdad, according to the Department of Defense, which gave no other details about his death except to say it was under investigation.
Patrick Farrow told The Associated Press after his nephew's May 25, 2008, death he felt as though he had been "kicked in the stomach."
"I've been opposed to this war since the beginning," Farrow said then. "This lying Bush administration has gotten into this thing that has now killed my nephew. It's up close and personal, and I am deeply angry."
