Monday, November 20, 2017 marks the three year anniversary of the unsolved murder of 54-year-old Melissa Millan of Simsbury.
The NBC Connecticut Troubleshooters have learned from a source close to the investigation that investigators have been able to identify a suspicious vehicle seen in the area on surveillance video around the time of Millan’s murder back in 2014.
Millan's bloody body was found by a passerby on Ironhorse Boulevard after she was stabbed once in the chest while jogging.
The Troubleshooters have learned more than 100 items of evidence have been provided to the State's Division of Scientific Services.
The evidence includes digital and biological items, including reflective wear and a headlamp the 54-year-old mother of two was wearing when she went out for a jog on that November day.
A source close to the investigation also said police have been able to identify a suspicious vehicle with area surveillance footage. Investigators are trying to identify persons of interest seen in the area at the time of the Mass Mutual senior vice president's murder using those same surveillance videos.
NBC Connecticut asked Deputy Chief State's Attorney Len Boyle about Millan's job at Mass Mutual.
"I hesitate to call anything a theory. Certainly, it’s an aspect of her life that has to be examined because any person involved in any aspect of her life, personal or professional, might have some information we need to pursue and we will pursue," Boyle said.
Neither Simsbury police nor the Office of the Chief State’s Attorney will confirm whether Millan had her cell phone on her when she was murdered. Both agencies have stated interviews are being redone, which may lead to new details.
In addition to redoing interviews, some of the digital and biological evidence collected locally by state police and the FBI is being retested using more sophisticated methods.
Now, authorities said they need to speak to anyone in the area of Millan’s murder which was around 8 p.m. on Nov. 20, 2014, along Ironhorse Boulevard.
"Anything you saw could be of value to us when put together with other information and evidence we have developed. The smallest piece of information- even though the person who holds it might think it’s innocuous- could be critical to our investigation and we encourage people to come forward," Boyle said.
Authorities want anyone with information on Melissa Millan’s unsolved murder to contact the Cold Case Unit tip line at (860) 548-0606 or call toll free at (866) 623-8058.
Mass Mutual is offering a $40,000 reward for information leading to an arrest.
NBC Connecticut left messages for Melissa’s brother who lives out of state and haven’t heard back.
Millan's ex-husband doesn’t currently have a comment.
