Mark Morales, CNN Mark Thomas Ryan arrived at his in-laws' Phoenix, Maryland, home with a loaded handgun tucked in his pocket. Hours earlier, local law enforcement had issued a temporary restraining order against him, after his wife alleged Ryan had struck and threatened her the night before, according to court records. Now, on the home's enclosed patio, Ryan confronted his father-in-law, a well-respected Maryland attorney named Robert MacMeekin, who had taken in his daughter and grandchildren.
