Sandra writes that Sinéad has "blonde hair, blue eyes, a slim build, 5’11 and speaks with an Irish accent."

In an update on March 22, Sandra wrote that her older sister "was last seen on March 11 wearing a white coat, white knit hat & black boots. Sinead was going to collect her dog Flossie a female, microchipped German Shepard dog.

"Sinéad left Lowell and travelled to collect Flossie from a friend in the NH [New Hampshire] area.

"She was going to go for a walk with Flossie before heading back home to Lowell.

"Her car was found parked near Ossipee Lake NH. Sinéad & Flossie haven’t been seen since."

Addressing her sister, Sandra said "our relatives finally made it through all of the red tape that stopped them from traveling to you from Ireland. They are there now, they will find you!"

She added: "Please keep looking for Sinéad & Flossie, please keep checking your land, sheds & cameras.

"We ask those that go looking for Sinéad to please stay safe, make sure a loved one knows exactly where you are going."
