Investigators understand night watchman dos Santos, who also died from his injuries, had planned the attack as they found gallons of fuel at his home.
A police spokesperson said: ‘Investigators believe the crime was premeditated and through diligent research they found gallons of fuel at the residence of the perpetrator.
‘It was also found that Damiao symbolically marked the date of his father’s death, three years ago as the date to carry out the attack.

Four died at the scene and two more plus the teacher died later from their injuries. Another 23 victims are still being treated at hospital, seven in a critical condition.
It has been alleged the guard, who had worked at the nursery for nine years, ’embraced’ some of the children while he was burning, causing them to catch light.

Speaking to Minas media, Mayor of Janauba, Carlos Isaildon Mendes said there was no indication that Santos was about to carry out the atrocity. He had no prior record of problems at work.
Mr Mendes said: ‘This is a very complicated situation. This was a decent employee who was on holiday from work.
‘I had just returned from visiting the nursery when I was told (Damiao) knocked at the gate saying he wanted to deliver a medical certificate because he claimed he was not feeling well.
‘He has been an employee since 2008 and has never had a bad record so we could never have anticipated something of this nature happening.’
According to a spokesperson from Janaúba city authority, Damiao went to the nursery carrying a pink backpack.

The spokesperson said: ‘Staff at the nursery found it strange that he chose to ring the bell and that he was at the nursery outside of working hours.
‘But he said he was there to deliver a medical certificate.
‘We believe he was carrying a bag of flammable liquid, possibly alcohol or gasoline in his backpack, which he used to set fire to the victims and himself.
‘Staff at the nursery said he poured the liquid over the children and set fire (to himself and to them). We were also told he embraced some of the children which caused their bodies to burn.’
