At least we know the cause now:
According to Vanguard, the Traditional ruler of Oworonsoki, Oba Basiru Oloruntoyin Saliu, who spoke to Vanguard in a telephone conversation said as soon as the incident occurred, said the collapse of traditional rites in the area may be responsible for the crash. He said,
The government no longer pays attention to traditional rites which is necessary to prevent such occurrences. For instance, how many times have we appeased the goddess this year? An occurrence like this may be caused by the goddess because no human being can depict the depth of the lagoon; but if the goddess is appeased, she would have prevented such occurrence.
