LEE COUNTY, Fla.-  Chad Moreland asked a judge if he could take back his guilty plea in Jerry Rabon's 2007 murder. A surveillance video shows Moreland and his sister breaking into the store and demanding cash. Moreland later shot Rabon to death.

Moreland says he did not understand what he was agreeing to when he entered a guilty plea in exchange for a life sentence. If convicted at trial, he would either face life in prison or the death penalty. But Moreland says his lawyers told him he may only get 40 years under the plea deal.

Both of his lawyers told a judge they fully explained the deal to Moreland, and he willingly went along with it in November.

The judge closed the book on the case, saying his guilty plea stands because he entered it willingly and no one forced him.

Rabon's mother says she finally has justice more than four years later. But there will always be one painful memory that weighs on her mind.

"I never got a chance, he never said goodbye to me while he was in the hospital. He was never conscious. I promised him the world if he could come out of it and say goodbye to me and tell me how he was feeling. I didn't have that opportunity and I don't wish that on anyone," said Gail Peluso.
