A US man accidentally killed his 33-year-old wife with a homemade cannon when the contraption went off and fired a projectile into their mobile home, police said.
The man, who had been drinking, was "freaking out" when emergency responders arrived at the scene in Potrero, near the Mexican border in southern California, said a spokesman for the California fire protection service.
A four-year-old child was also inside the home when the cannon went off for an unknown reason in the early hours, but was not hurt, said local homicide detective David Martinez.
The man was working with another person on the contraption shortly after midnight when it exploded, the Los Angeles Times reported. One man was taken to hospital with minor injuries. A neighbor was taking care of the child.
