I can’t imagine the terror that must have been running through the mind of the 74-year-old Southgate, Michigan homeowner just before 5:00 AM this morning as a home invader broke in.

The homeowner armed himself and stepped outside the bedroom to protect his cancer-stricken wife as she called 911.

The homeowner ran into the armed home invader. According to investigators, the home invader raised his weapon, and the homeowner was forced to fire to save his life.
