Two years have passed since Melissa Millan, a 54-year-old mother and insurance company executive, was stabbed and killed while jogging on Iron Horse Boulevard -- and the case remains unsolved.

Someone found Millan in the road around 8 p.m. on Nov. 20, 2014, and she was rushed to Saint Francis Hospital, where she died a short time later, according to police.

Police initially thought she might have been killed in a hit-and-run, but the medical examiner determined she died of a stab wound to the chest.

She had been jogging somewhere between Phelps Lane and Pent Road when she was stabbed on the busy street, which includes a heavily used bike trail, several restaurants and the Performing Arts Center at Simsbury Meadows.

In June 2015, a $40,000 reward was offered, but there has been no arrest.

Two years after the slaying, a memorial with a photo, a pumpkin, mementos and more marks the site where Millan was stabbed.

Bob Knight, who knew Millan and her parents, said last year he believed Millan's death might be tied to her work as an investigator for Mass Mutual Insurance.

But police have not nothing to indicate Millan's job had anything to do with her death.

Local police continue to investigate on a daily basis, interview people and take tips and calls.

The Federal Bureau of Investigation has also been involved in looking into the case.
