CASTLETON, Vt. — The brother of actress Mia Farrow has been found dead in his art gallery, and police said Tuesday his death is suspicious.

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.

State Police Lt. Timothy Oliver called Farrow’s death suspicious. He 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. Their relationship ended in scandal and New York tabloid headlines in 1992, when she found out he was having an affair with her adopted daughter Soon-Yi Previn, then 22.
