The coastguard boat delivered the deceased to Lampedusa, the stepping stone island for migrants between Italy and north Africa.
The big migrant boat had dozens of other north Africans on board.
Two other people are reportedly missing from the migrant boat.
A woman passed away and fell into the water and her four-month-old son, who was in her arms, drowned.
It had initially been reported that the baby had died while on the boat and the mother had thrown his body into the sea in desperation, but the reconstruction of what happened became clearer for investigators after they spoke to more of the survivors, with cultural mediators helping overcome some initial misunderstandings.
Furthermore, a man who was reported to have drowned after throwing himself into the sea after the infant, actually died after passing out and falling into the sea.
