The last defendant in the death of Derrion Albert has been sentenced, the Chicago Tribune reported.

Lapoleon Colbert, 20, was sentenced to 32 years in prison. He was convicted of first-degree murder back in June.

Colbert kept his hands folded on the defense table and frowned while the judge read his sentence, the Chicago Tribune reported.

Albert was 16 years old when he died in September 2009 after being beaten by a group of teenage boys.

A cell phone video showed the boys beating Albert.

A jury would later hear a tape of Colbert being interrogated by police and admitting he had participated in the beating.

This is my first offense, have mercy on me, Lapoleon would say in court, the Associated Press reported.

Colbert was the fifth and final defendant in the case to be convicted.
