Derbyshire Police have confirmed they launched an investigation into allegations of further offences committed by Mick Philpott.
Philpott and his wife Mairead were jailed in April after being convicted of the manslaughter of their six children. Jade, 10, and her brothers John, nine, Jack, eight, Jesse, six, Jayden, five, and Duwayne, 13, died following a fatal house fire at their Derbyshire home.
The father of Mairead Philpott, who was jailed for 17 years for her role in the house fire that killed six of her children in May last year, has said he does not support his daughter's appeal against the sentence.
Speaking exclusively to Daybreak, Jim Duffy said he "could never forgive her" for what she has done and that he believes she should have received a life sentence.
Martina Longworth, a partner at Moody & Woolley, said builders discovered Kevin Gough's body in the firm's chimney when they were carrying out work at the Grade II listed building.
She said she could not comment on whether the victim had died as part of a burglary and the sympathies of staff were going out to Mr Gough and his family.
It's very tragic, it's very sad for the man who was found there.
He must have family and friends around him and our thoughts go out to them.
Staff feel the tragedy.

"It is the council's intention to bulldoze the properties but we need to go through a number of legal loopholes first."
