The source further stated that the children were poisoned with the bread and chocolate the suspect gave them to eat.

"The woman and the suspect spent so many years loving each other after the death of her husband," the source said, adding that the couple were making plans to make their union official but the family of the woman denied the union.

The man got really angry when he learnt that his relationship with the woman was at the verge of collapsing.

The source said the man really invested much money, time and love to the relationship and he was not ready to just walk away like that.
