Lawyers for the former Indiana State Trooper convicted of murdering his wife and children, have filed their final appeal. David Camm's lawyers argued that his murder conviction should be reversed because another man was proven to be at the scene and was acknowledged to be involved. They also argue that the Floyd County Prosecutor failed to prove a connection between Camm and the other suspect, Charles Boney, during Camm's 2006 trial. Charles Boney was also convicted in the murders of the Camm family during a separate trial and is currently serving a 225 year sentence. Camm is serving a sentence of life without the possibility of parole. This is the second time Camm's been convicted and found guilty of murder.
