Fredericton firefighters made a grisly discovery on Sunday evening while inspecting a home on Aberdeen Street after a fire.
Fredericton Police Cpl. Sean Clark said the firefighters found a body in the attic.
Foul play is not suspected in the person's death as Clark said it looks like it was a suicide that happened some time ago. However, an autopsy has been ordered.
There is no missing person case report that matches the case.
Clark said the body was unrelated to the fire, which he described as suspicious in nature. The house fire displaced six or seven people.
The Red Cross helped some of those residents, while others found other housing options on Sunday.
The Fredericton police officer said the people inside the home had no idea there was a body in the attic.
The older Aberdeen Street home had been converted to apartments and had at least seven units.
One room was badly damaged in the fire, while other units had smoke damage.
The police arrested a male suspect in connection with the fire.
