Jurors were chosen Monday in the murder trial and opening arguments are expected Tuesday.
Albert, 16, was walking home from school when he was caught in a street brawl between rival neighborhoods. The suspect, who has not been identified because of his age, is one of five "main offenders who struck the critical blows," prosecutors said. Prosecutors said the teen struck Albert, a Fenger High School student, in the face with his fist "causing him to fall."
The four other suspects-- Silvonus Shannon, Eric Carson, Eugene Riley and Lapoleon Colbert-- are charged as adults. One of their trials will begin in January.
The suspect is the last to be tried in the September 24, 2009, beating of Albert in front of the Agape Community Center. A cell phone video of the attack gained national attention; President Barack Obama dispatched both United States Attorney General Eric Holder and United States Secretary of Education Secretary and Chicago's former schools CEO, Arne Duncan, to Chicago for a national dialogue on juvenile crime.
Albert's mother spoke with ABC7 on the anniversary of her son's death.
