On October 24, 1978, a deliberately set fire gutted an apartment building at 541-547 Chestnut Street in Manchester, New Hampshire, killing two residents. One victim was 53-year-old Pauline Miller; the other was 51-year-old Ray Blanchette. Both died of smoke inhalation after the State Fire Marshal concluded the blaze had been intentionally started, transforming the incident into a double homicide.

Investigators treated the deaths as a criminal act, but despite subsequent inquiries no arrests were ever announced and no suspects were publicly identified. The case remains open and unsolved on the New Hampshire Department of Justice list.

Did anyone in Manchester living near Chestnut Street in 1978 notice anything unusual that night or have information that could help finally close this case?
