Florida toddler's cause of death determined after alligator attack.

The Florida toddler who was found in the mouth of an alligator last month died by drowning following the brutal murder of his mother, according to a medical examiner. The boy’s father has been charged with two counts of first-degree murder in the deaths of his son and the mother. The father allegedly stabbed the mother more than 100 times and then took his young son to an alligator-infested lake and either placed or threw the tot in the water.
