A deliberately set early-morning fire at 314 Islington Street in Portsmouth, New Hampshire, claimed three lives. On Saturday, October 11, 1986, the blaze reported about 3:25 a.m. killed 29-year-old Joseph A Poulin and 24-year-old Terry Giles. A third resident, 39-year-old Linda Plummer, was severely burned and later died of her injuries on March 30, 1987, at Massachusetts General Hospital.

Investigators determined the fire was not accidental and classified the deaths as homicides. The fatal arson remains unsolved and no suspects or arrests have been publicly identified. Authorities continue to seek information that could help identify who set the fire and bring justice for Poulin, Giles, and Plummer.

If anyone has information about the 1986 Islington Street fire or remembers details from that night, please come forward.
