(Newser) – A 33-year-old San Diego-area woman died early this morning when a cannonball—fired by a man who is either her husband or her boyfriend—slammed into her mobile home. Authorities found the woman dead when they arrived around 12:15am, and the man admitted to igniting what the San Diego Union-Tribune refers to as "makeshift artillery." He was injured in the leg after igniting his contraption; a four-year-old who was in the home at the time was not hurt. Homicide detectives and the bomb squad are investigating.
