Helena Fells, 49, of Lowell, Massachusetts, was last seen on November 26, 2006. Her car was found parked near the Merrimack River in Lowell, and police dogs tracked her scent to the river’s edge. Initial searches turned up no sign of her.

In 2011 an environmental cleanup crew found partial remains along the Merrimack River in West Newbury: a foot and an ankle bone with a shoe. DNA testing later confirmed the remains belonged to Helena, giving her family some closure after years of uncertainty. Family members had questioned whether foul play or suicide could explain her disappearance, but many details about what happened on the day she vanished remain unclear.

Did anyone in the Lowell or West Newbury area have contact with Helena around late November 2006 or notice anything unusual along the Merrimack River?
