According to the limited info I got about this video, four people died in the accident, and one of them was an infant only 10 days old. I didn’t get any further info.
After the frog-posed female fatality is shown, the camera glances over a slightly beat up motorcycle, which leads me to believe this was is vehicle involved in the accident.
The child is shown at around the 0:19 mark, and it does indeed seem to be dead, and does seem to be very little, perhaps mere days old. After that, the footage shows two men in the gutter. One appears to be dead, the other one is injured and grief stricken by the deaths of his mates.
Unless I’m missing something, my conclusion is that 4 people got involved in the accident, 3 of them died. Also, unless my ears are deceiving me, this happened in a Spanish speaking Latin American country.
