Alcohol a factor in woman's cannonball death, authorities say

Authorities said the cannonball that struck and killed a 33-year-old woman in San Diego County was homemade and that alcohol was involved in the incident.

The woman's husband and another man were working on a cannon shortly after midnight outside the couple's mobile home when it exploded, according to a Cal-Fire spokesman. One of the two men was sent to the hospital with minor injuries.

The incident is being investigated by the San Diego County Sheriff's Department.

Few details were immediately available, and it's unclear exactly what killed the woman.

The incident occurred in a mobile home park in Potrero on the Mexican border.
