West Tisbury selectmen voted to promote police officer Garrison Vieira to the rank of corporal on the recommendation of police chief Dan Rossi on Wednesday.

“I’d be honored to have the position and I look forward to the responsibilities,” said Mr. Vieira.

Mr. Vieira has been a full-time officer in the department for seven years and will now act in a supervisory role to other patrolmen.

Selectmen also provided Nick van Ness five minutes to present his argument for a petition article that appeared on the annual town meeting warrant calling for an investigation into 9/11. Selectmen believed that Mr. van Ness received a rude reception at the end of the meeting as voters filed out of the auditorium. Mr. van Ness, a former naval demolitions expert, believes the buildings were brought down by controlled demolitions.

Selectmen also approved the annual Mayfest and yard sale at the Island Children’s School on May 14 from 10 a.m. to 2 p.m. and a Martha’s Vineyard Garden Club art show at the Old Mill from July 8 to July 10.

Selectmen also reappointed town poet laureate Fan Ogilvie to her third and final one-year term and read from the resignation letter of longtime planning board member David Douglas, who wrote that his time serving the town had given him “much pleasure.”
