Waseem Daker Sentenced To Life Plus 47 Years For Slaying Of Flight Attendant Karmen Smith (VIDEO)

A 35-year-old man found guilty in the 1995 killing of a flight attendant has been sentenced to life in prison plus 47 years.

Waseem Daker insisted at sentencing Monday that he was wrongly convicted of killing Karmen Smith and repeatedly stabbing her 5-year-old son Nick in an Atlanta suburb.

The son, now 22, survived the attack in Marietta, according to the Associated Press.

"I did not kill Karmen Smith. I did not stab Nick Smith," Daker told the judge. "I hope that one day the truth comes out."

Prosecutors said Daker killed Smith and attacked her son because he was obsessed with the flight attendant's neighbor. Authorities long suspected Daker but said they didn't link him to the attack until 2009.

Jurors last week found Daker guilty of murder and several other counts.

Cobb County Superior Court Judge Mary Staley called Daker “a master manipulator” and told him, "I hope you never leave prison because that will be just,” according to ABC News.

The trial was notable for many reasons, including the fact Daker represented himself and cross-examined both the the boy he attacked as well as Karmen Smith's former roommate, Loretta Spencer Blatz, the woman who he was convicted of stalking back in 1996.

Blatz, now 47, met Daker playing paintball and he attempted to date her. When she showed little interest, Daker began to stalk her. He called her incessantly, followed her, and even broke into her home to hide inside.

After Smith's murder in 1996, Daker was arrested again, convicted of stalking Blatz, and served 10 years in prison before his release in 2006.

Police were unable to connect Daker to Smith's death until 2009, when DNA evidence placed him at the scene of the crime.

Prosecutors said when Daker, now 35, was arrested, officials found rope, handcuffs and at least two "how-to" books: "How to Get Away with Murder" and "Kill Without Joy."
