One person has died and two have been taken to hospital after a house fire in Kirton near Boston on January 1.
Emergency services were called to the blaze at around 3am at the detached house in Peartree Road.
Police and fire investigators continue to examine the scene of the fire.
Because of the ferocity of the fire, it’s going to take several of days to establish how the fire started, police said.
Police are in the process of contacting who they believe to be the next of kin of the person who died and will then carry out formal identification.
The investigation is being conducted by officers from the East Midlands Specialist Operations Unit.
Officers are appealing for anyone who has any information about the occupants of the address or anyone who was driving in or near Peartree Road up to 3am and may have dash cam footage of the house before the fire started.
