Fallen rapper Dolla's family celebrated his 22nd birthday last week (Nov. 25) with the release of his latest mixtape, 'The Miseducation of Dolla.'

The Konvict-signed rapper, born Roderick Anthony Burton II, was shot and killed in Los Angeles on May 18, 2009, by Aubrey Louis Berry, who was apprehended at LAX shortly after, attempting to flee.

"Just a few hours before the incident, I spoke to my son and he was on his way home catching a flight out. I stay close to the airport, so he used to stop by," Dolla's mother, Dawnee Robinson, said in a recent interview. "He told me what he wanted for dinner. He wanted some yellow rice, cabbage and chicken wings. So I went to the store and made sure I had everything. So when I got the call, I was cooking his dinner."

Dolla had a deal with Dreamworks early in his career, but when that didn't work out, he signed with Akon's Konvict Muzik in 2007. His single "Who the F--- is That" featured Akon and T-Pain. He was working on his debut when he was gunned down at Los Angeles' Beverly Center.

"My son was always working, always in the studio," his mother said. "He spent a lot of time at home with us when he wasn't on the road. So you know, whatever caused this person to murder my son, I'm still in total disbelief."

Dolla's killer was charged with murder and assault, but has pleaded self defense, claiming that the rapper and a local gang threatened him, instigating the shooting. Prosecutors are said to be seeking the death penalty, and he is currently being held on $2 million bail.

"All I know is that [it] is not OK to go around shooting and killing people," Robinson said. "That's not what I believe in. That's not what my son believed in and I feel that anyone who is so bold to take another life, for no apparent reason, I feel that they should be prosecuted with full extent of the law and that's how I feel."

Dolla's mixtape, 'The Miseducation of Dolla' is available now, and includes two unreleased tracks, "Ghetto Prayer" and "Gonna Be Alright."

"His legacy is a great one," Dolla's mother concluded. "I believe that you know in due time you know Bu [Akon's brother/business partner], Akon and Damian Jackson, Dolla's manager and mentor will make the step to put things out really soon. The mixtape came out today on his birthday as a free download. We just want him to heard."
