A New York City woman who disappeared on a walk while visiting her mother in Massachusetts has been found slain in the woods, investigators said.

Worcester District Attorney Joseph Early Jr. said Monday that 27-year-old Vanessa Marcotte was reported missing after failing to return from a Sunday afternoon walk in Princeton.

Her body was found Sunday night by a state police canine unit about a half-mile from her mother's home. Authorities said her death appears to be a homicide. An autopsy is scheduled.

"People should be concerned," Early said.

Police Chief Michele Powers has urged town residents to remain vigilant.

No other details were immediately released.

The rural town of Princeton has about 3,500 residents and is 40 miles west of Boston. Early says Marcotte grew up in nearby Leominster.
