Edul Azeez admits he should have come forward a long time ago.
"I apologize to all of you," Azeez said in court on Friday.
He was one of five young men who admitted to burglarizing the car of David Hessler.
On November 14, 1995, the 30-year-old computer programmer went outside his University City home to check on his car when he was shot and killed by one of the five car burglars.
During his sentencing, Azeez told the victim's family he had no intention of killing anyone and didn't come forward sooner because the shooter, Alvin Timbol, threatened him.
"I am sorry for what I put you through," Azeez tearfully told Hessler's family.
For nearly 15 years, Hessler's family had no idea who killed him, or why. But last year, the cold case was solved thanks to new fingerprinting technology.
The five suspects involved in the crime were arrested and all of them convicted, including Timbol who pleaded guilty to murdering Hessler and is now serving life in prison.
"No words can express how sorry I am for your loss," said Edul's wife and mother of their infant child.
"I am even sorry that I am involved with someone that was part of the incident," Domingo Azeez told Hessler's family.
Azeez sobbed as the judge sentenced him to 11 years in prison.
Khoi Bruster, 33, was also sentenced on Friday to 11 years in prison. His mother spoke on his behalf.
"I know within my heart that he is sincerely sorry and I am too," Susan Miller told the judge.
Hessler's family did not comment during the sentencing.
