Police investigate a decades-old cold case in which a woman died more than 30 years ago. According to reports, detectives have recently served an 86-year-old man—identified as the woman’s husband—with a search warrant and interviewed him as part of the renewed investigation. The renewed activity follows indications that investigators may also be looking into a potential second killing involving the man’s first wife, though details of that suspected link are not provided in the available reporting. The current probe centers on the long-closed death of his wife, with investigators using new investigative steps such as executing search-related actions and conducting an interview. The reports describe the husband’s involvement at this stage as being under investigation rather than stating that he has been charged. No further information about evidence uncovered, investigative findings, or the identity of the earlier victim is included in the supplied material. The case remains under police examination as detectives follow leads related to the woman’s death and any additional allegations connected to the suspect.
