Police say the two men had argued over their dogs for the past five years. The fence between their neighboring condos was being repaired - so both of the men's dogs had wandered between yards.
Andersen confronted Cardoza Thursday afternoon - when Cardoza was trying to get Andersen's dog out of his yard. The two got into a violent fight. A short time later - Cardoza was shot and killed just feet from his front door.
Chief Dyer says the tragedy has now changed the lives of the victim and suspect's widows forever. "We have two widows that are left behind, that now live next to each other, trying to make sense of why both of their husbands are dead."
Police say Andersen left his wife two voice messages before taking his life in the parking lot at River Park. Police are waiting on toxicology reports on both men.
