Yes, they got the gun type from the bullets.....and that is it. If Ritchie decided last month to move to Canada and become a priest, you would have five cold cases that would never been solved by APD despite of the gun and the bullets. Ten years from now, ADN would do an anniversary special on the killings and maybe APD would reveal what little they know and how much they don't know. We all got lucky in this case, thanks to two good officers who could shoot straight and true. They deserves medals and honors!!
