Prosecutors say an 18-year-old delivered the "knock out" punch of a Chicago Honors Roll student that was beaten to death on his way home from school, MyFOXChicago.com reported.

Eugene Bailey is one of four suspects charged in Derrion Albert's death. He was denied bail at a court hearing Tuesday and remains in jail.

Cell phone footage shows a group of teens kicking and striking Albert with splintered railroad ties after the Christian Fenger Academy High School sophomore left school Thursday.

The three other suspects, Silvonus Shannon, 19, Eugene Riley, 18, and Eric Carson, 16 are also being held without bail for their alleged roles in the beating.

The violence stemmed from a shooting early Thursday morning involving two groups of students from different neighborhoods, said Tandra Simonton, a spokeswoman for the Cook County prosecutor's office. When school ended, members of the groups began fighting near the Agape Community Center.

During the attack, captured in part on a bystander's cell phone video, Albert is struck on the head by one of several young men wielding wooden planks. After he falls to the ground and appears to try to get up, he is struck again and then kicked. Simonton said Albert was a bystander and not part of either group.

Albert's aunt, Rose Braxton, told CBS's "The Early Show" on Tuesday that her nephew was a "great kid" with an "easy-going temperament."

For Chicago, a sharp rise in violent student deaths during the past three school years — most from shootings off school property — have been a tragedy and an embarrassment.

Before 2006, an average of 10-15 students were fatally shot each year. That climbed to 24 fatal shootings in the 2006-07 school year, 23 deaths and 211 shootings in the 2007-08 school year and 34 deaths and 290 shootings last school year.
