Phoenix police need your help to solve a murder mystery.

Nancy Newton was killed in her own home back in April 2012. Police say a man broke in and then assaulted the 82-year-old woman.

Newton lived alone at the home near 28th Street and Earl Drive.

Police say it took Newton more than an hour after the attack to reach the phone and call police.

Newton was rushed to the hospital but died four days later. The Medical Examiner determined the injuries she sustained contributed to her death.

Police released a photo of a man spotted near Newton's home but are not calling him a suspect.
