There's no trial to prepare, no jury to persuade, no judge to hand down a sentence.
Wade Michael Page is dead, killed by police after fatally shooting six people at a Sikh temple outside Milwaukee.
Although detectives are pursuing leads in several states, their findings might never be presented in court.
But investigators still want to know the full story behind the attack, especially a motive that might provide answers to devastated Sikh families and valuable information about white supremacists.
At the moment, detectives are sifting through the gunman's life, assembling the biography of an Army veteran who apparently had few relatives, a spotty work history and a thin criminal record.
They have warned they may never learn for certain why he attacked.
