Investigators in Guyana believe that the fire incident which murdered 19 mostly girls trapped in a school dormitory was deliberately set by a student who was upset that her mobile phone was confiscated, a top official said.
The suspect in the fire late Sunday (local time), who is among several injured people, had been disciplined by the dorm administrator for having an affair with an older man, National Security Adviser Gerald Gouveia said.
The student allegedly threatened to torch the dorm and later set a fire in a bathroom area, Gouveia said.The fire raced through the wood, concrete and iron-grilled building after it had been locked for the night by the dorm administrator — or house mother — to prevent the girls from sneaking out. 
“She did this out of love for them. She felt she was forced to do so because many of them leave the building at night to socialise,” Gouveia added.“This is a very sad situation, but the state is going to work with the students and the families to provide all the support they need.”
All but one of the victims were Indigenous girls aged 12 to 18 from remote villages served by the boarding school in Mahdia, a mining community near the Brazil border. The remaining victim was the 5-year-old son of the house mother.Many of the victims were trapped as the building burned, though firefighters were able to rescue people by breaking holes through one of the walls.“The house mother was asleep at the time inside the building but panicked and could not find the right keys to unlock the building from inside but she made it out. She also lost her five-year-old child in the fire,” Gouveia said.Many of the nine people hospitalised are in serious condition.
Guyana’s government has also accepted offers from the US to send forensic and other expert teams to help with the investigation. The government also was sending specialists in DNA identification to help identify remains of 13 of the 19 victims who died at the scene.
