The family, led by Alhaji Muritala Alarape Salaut in an interview said it could not be true that the victims died from inhaling gas emitted by the generating set as there was no sign of such a thing in the house.

Police authorities and the state association of butchers have also expressed disagreement on the report.

Ayinla and nine other members of the family were found dead last week in their apartment by a neighbour who reported to the police before the bodies were evacuated to State Hospital, Adeoyo where a test was later conducted on the deceased to ascertain cause of death.

The police and the butchers association contested the result of the test, insisting that there was no evidence that the Ayinla's put on the generating set before they went to bed on the day of the incident.

The State Police Public Relations Officer (PPRO), Mr. Femi Adedeji, told The Guardian that the generator was not on when the police team visited Ayinla's house adding that it was inside the kitchen when they got there.

He said, "there was no wire connecting the generator to the house to show whether it had worked and later went off."
Contacted, the General Secretary of Oyo State Butchers Association, Mr. Tunde Ajala, also faulted the autopsy report.

He said that the generator was used during the day when Ayinla threw a house-warming party, claiming that other factors must have been responsible for the death of the 10 members of the family.

According to him, "the generator was put off before all of us left Ayinla's house. After the party, they lighted candles in the evening. Why are they saying that it was poisonous gas which the deceased inhaled killed them."
Ajala, who said he suspected foul play, urged the police not to limit their investigations to the theory that the victims died after inhaling poisonous gas. He stressed that the outcome of the medical test was not acceptable to members of his association.

The PPRO, however, said that a forensic test being conducted in Lagos on the left over rice meal found in the Ayinla's house would offer more useful clues in unraveling the actual cause of the death.
