Deputies with the San Diego County Sheriff's Department received a 911 call around midnight from a man who said his wife was killed by a homemade cannon that accidentally discharged.
Homicide investigators arrived on the scene along with U.S. Border Patrol agents. They discovered that two men had been working on the Do-it-Yourself cannon outside of a home in the Twin Lakes Resort mobile home community.
While the amateur pyrotechnicians were fiddling with their creation, the cannon unexpectedly backfired and sent a projectile into the nearby home.
The 33-year-old woman struck by the cannon fire was dead by the time police arrived. The coroner's office listed the cause of death as "injuries suffered from a projectile." One of the two men working on the cannon was also injured. He was taken to Sharp Memorial Hospital with unknown injuries.
Although initial reports say the weapon was constructed by the men, Cal Fire spokesperson Mike Mohler could not confirm whether or not the cannon was actually homemade or not.
