An Anderson man will go on trial next month for fatally stabbing a man he allegedly found having sex with the man’s ex-wife, then kidnapped his family and headed to Minnesota las summer. The man is 25-year-old Mark Emerson. He’s reportedly planning to argue self-defense, according to a notice filed this week in Madison Circuit Court. The victim, 25-year-old Cody Gay, was from Indianapolis. His body was found wrapped in a quilt in the basement of the home the Emerson’s rented. Emerson had a protection order against him by his ex-wife after an incident last April where he was charged with domestic battery, felony criminal confinement, intimidation and strangulation.
