Suspect Arrested in Killing of MassMutual Executive

Millan, 54, was found near a running path in Connecticut almost four years ago. Months later, an anonymous donor put up funds for a $40,000 reward to find the killer. The insurance executive worked in the retirement-services business for Springfield, Massachusetts-based MassMutual, which she joined in 2001.

Around 2005, she helped start a Council of Disability Insurers. She was active in efforts to promote the idea that executives needed more and better life and disability benefits.

"Melissa Millan was an incredible person and outstanding leader, and we were fortunate to have her as a part of our MassMutual family for more than a decade," Michael McNamara, a MassMutual spokesman, said in an emailed statement. "We are encouraged to learn that there are developments in her case, and continue to keep Melissa and her family in our thoughts."
