Staff of the Ellacoya Bar & Grille and Ellacoya Country Store in Gilford, New Hampshire experienced a strange event on March 17. Video footage from the surveillance camera of the business shows a glass object flying from a counter and breaking into pieces on the floor. No employees were around at the time of the incident. On the video, two staff members can be seen rushing in to the store area to investigate what the sound was.
Many people that have viewed the video believe this is some type of hoax or publicity stunt. Others think it is proof of the paranormal.
"Sorry disbelievers, I have seen things come straight off shelves and fall to the floor. It happens. I just accept it now and go about my business," employee Susan Rice said. Staff of the business also said that they have contacted paranormal investigators to investigate the building.
The Ellacoya Bar & Grille is located at 2667 Lakeshore Road, in Gilford, New Hampshire. More information can be found by visiting the business' Facebook page.
