Deputies say a man called 911 to report his wife may have been killed with a homemade cannon by accident.
Investigators along with U.S. Border Patrol agents responded to Potrero Valley Road around 12:30 a.m. Tuesday.
Two men were working on the cannon outside the home in the Twin Lakes Resort mobile home park when it fired, sending a projectile into the home.
