The woman identified as Tawa and her husband were reportedly found unconscious while their baby was already dead in the room after going to bed on Thursday evening hale and hearty.
Tawa later died in the hospital while the husband is said to be in a critical condition.
A source who spoke to The Punch said the couple bought a new generator a few days before the incident and they put on the generator on Thursday evening before going to bed, raising suspicion that the incident must have been caused by the generator’s fume.
