Tracy is the sister of Massachusetts State Police Col. Kerry Gilpin. The family has been hoping for an arrest for years and offered a reward for information that helped solve the murder.
Kerry Gilpin released a statement shortly after the announcement of the arrest, thanking all who helped solve murder, including information from the public.
"For the past three decades, we have remained hopeful that Tracy’s murderer would be identified. The much-welcomed news of an arrest in the case leaves us cautiously optimistic that justice for Tracy is within reach. My thoughts today are not just with my own family, but also with all the families who have lost loved ones to violence. We will continue to work tirelessly to find justice for all murder victims," she said.
