According to initial findings, a toddler shot his mother in Florida while watching a video.
The woman fell over during the switch, said the Altamonte Springs police.
Before that, a noise could be heard and a toddler could be seen, said a participant in the video circuit of the police.
This then alerted the emergency call.
The rescue workers could no longer help the woman - she was found with a fatal gunshot wound to the head.
Investigators assume that the child caused the injury.
It had found a loaded gun that had been left unsecured in the apartment by an adult.
