Winslow Township grandmother still missing 3 years later, as family searches for answers

It's been three years since a grandmother disappeared in South Jersey. 63-year-old Norma Yates was last seen in her trailer home on Vineyard Road in Winslow Township, Camden County. Her ID, cell phone, and cigarettes were all left behind. Nichole Ennis is her daughter, and is still looking for answers. The Camden County prosecutor's office is now leading the investigation. The family has also hired a private investigator. They installed digital billboards this month to remind people Yates is still missing. Ennis says she's determined to find her. Ennis tells NBC 10 she's using this experience to help other families with missing loved ones, and to improve the investigative process. (Photo: Erman Gunes/Getty Images)
