A toddler shot and killed his mother as she changed his young sister’s nappy, after the child found a handgun under the sofa in Tulsa, Oklahoma.

The 26-year-old was shot in the head with a ‘large calibre’ weapon, police said.

Police say that the child kept saying, ‘Mommy shot,’ before he was taken away for interview by police.

Sergeant Dave Walker said, ‘There were several guns in the house: this appears to have been a large calibre handgun.
