Jury selection began today in Dukes County Superior Court for the murder trial of an Aquinnah man.

Ovando Eghill, 32, is charged with second degree murder and assault and battery with a dangerous weapon after he allegedly fatally stabbed an Edgartown man, Michael M. Trusty, on June 14, 2011.

According to police, the incident took place outside a Spring street home in Vineyard Haven. Mr. Eghill’s wife was previously married to Mr. Trusty, and both men were at Spring street to visit their children, police said.

The two allegedly became involved in a confrontation, and a police report said that Mr. Trusty held a machete over Mr. Eghill’s head and attempted to strike him. Police said Mr. Eghill blocked the attempt and then allegedly stabbed Mr. Trusty with a work knife from the waistband of his pants.

Mr. Eghill’s attorney, Robert Jubinville, said at the time that his client acted in self-defense.

Mr. Trusty, 45, later died at a Boston hospital. In October 2011, Mr. Eghill was indicted by a grand jury and arraigned in Superior Court; he has been free on $10,000 bail since that time.

Cape and Islands first assistant district attorney Michael Trudeau and assistant district attorney Laura Marshard are representing the commonwealth. Superior Court Judge Hon. Gary A. Nickerson is presiding.
