But when the homeowner refused to let them in, the gunman started to shoot, striking Miller in the chest. He died a week later. Two other men inside the home were injured but survived.
Peterson, 25, pleaded guilty to third-degree murder and related counts and was also sentenced to 19 to 40 years in October, said Assistant District Attorney Gail Fairman. A jury convicted White in October.
Fairman told Carpenter that White was just as responsible for Miller's death, saying Miller was "having a party with his friends and he's killed by these three young men who saw him as prey."
She said White waited outside and was planning to run in to assist in the robbery but instead ran away after the shooting started.
White, she said, had no excuse to be involved in the robbery, given that he was employed, had no mental-health issues and was a high-school graduate who had several years of training from Lincoln Technical Institute.
"He has no excuse except that he's greedy and wants a part of that money," she said.
"I will never try to justify the actions that brought me here today. I just hope you can find it in your hearts to forgive me," White said to his victims and their families.
Defense lawyer Joseph T. Schultz said an appeal would be filed, possibly related to the fact that White's trial attorney, Gregory Noonan, 53, has been disbarred for professional misconduct and a drug arrest.
Noonan, of Lansdale, was arrested Dec. 20 for selling Oxycodone pills to an undercover Montgomery County police officer in November. Court records indicate he is still jailed.
"The question is, how good of a job did his attorney do for him? You have to call it into question," Schultz said.
