Some victims of the Aurora theater shooting say they want to hear the gunman apologize. Others are telling the court they hope James Holmes will be killed by inmates once he enters prison.

Jansen Young is among those speaking at this week's formal sentencing hearing. Her boyfriend died trying to protect her during the attack. 

She says Holmes should try to atone for his crime by giving researchers access to his thinking.

"The defendant surely must know the diseased mind enough that doctors, scientists, and agents of law may benefit from the information he has," Young said. 

Victim impact statements are expected to wrap up Tuesday, with the judge giving his final sentencing decision tomorrow.
