Artillery In The Mobile Home Park

Events are still unclear:

A US man accidentally killed his 38-year-old girlfriend with a homemade cannon when the contraption went off and fired a projectile into their mobile home, police said.

...Fox, who had been drinking, was “freaking out” when emergency responders arrived at the scene in Potrero, near the Mexican border in southern California.

The couple’s young daughter and three other adults were not injured when the cannon went off for an unknown reason in the early hours, said local homicide detective David Martinez.

...Doctors took Fox to hospital in San Diego for treatment for leg injuries he suffered when the makeshift mortar went off. He was then arrested on suspicion of detonating an explosive device in a manner resulting in death.

Initially the incident was reported as an accident, but Martinez said Fox’s motives were unclear, telling reporters it was “too early to say it was accidental.”
