CASTLETON (Vermont) - ACTRESS Mia Farrow's brother, a sculptor, killed himself at his art gallery in Vermont, state police and a spokesman for the actress said on Wednesday.

Patrick Farrow, 66, died of a single gunshot wound to the head late on Monday night in his studio, a converted church, authorities said.

Farrow and his wife, Susan, regularly walked along the main thoroughfare in Castleton, a central Vermont town of about 4,300 not far from the New York border.

Police had initially classified Farrow's death as suspicious, but later said the medical examiner's ruling of suicide was consistent with evidence found at the scene.

Patrick and Mia Farrow are the children of director John Farrow and actress Maureen O'Sullivan.

Mia Farrow's movie credits include Rosemary's Baby, Hannah and Her Sisters and Crimes and Misdemeanours.

'The family of Patrick Farrow is grieving the tragic loss of their beloved husband, father, grandfather, brother and uncle who sadly chose to take his own life,' said Mia Farrow's manager, Laura Berwick.

'They greatly appreciate the support of their friends during this difficult time.'

Farrow was a professional sculptor for more than 35 years. The website for the Farrow Gallery says it sells jewellery and mixed-media works of art. The gallery was quiet on Wednesday. -- AP
