A woman was found dead near a construction site in Derry, New Hampshire, on Monday, police said, asking for help identifying her.

There was no indication of foul play in the death of the woman, whose body was reported by workers about 1:25 p.m. on Birch Street near Rockingham Road, according to Derry police.

The woman was seen on video days before walking to the area alone, apparently sick or impaired, police said. She stumbled and fell as she walked past a retention pond and landed near it.

The location is hard to see from a nearby business and driveway, according to police.

They described her as being about 45 to 50, with dark blond, slightly longer than shoulder-length hair. She wore a black sweatshirt, a floral skirt about mid-thigh length and grey sneakers, but no purse, cellphone or ID.

Anyone with information about the woman’s identity was asked to call Derry police at 603-432-6111.
