Chicago police may be closer than ever to getting justice for 9-year-old Tyshawn Lee. Finally, an arrest... but cops say at least two other killers may be involved.

Corey Morgan is charged with first-degree murder and is being held without bond. Morgan was initially named as a person of interest in the case, questioned, and then released after posting bond on a weapons charge.

A second man is in custody on an unrelated charge, but his identity has not been released.

The third suspect -- Kevin Edwards -- remains on the run.

Police say all three are in the same gang. They reportedly lured Tyshawn to an alley earlier this month, then "assassinated" him to get back at his father -- who's also a suspected gang member. But Tyshawn's dad repeatedly denies having anything to do with his son's murder.
