Corey Morgan charged with first degree murder of Tyshawn Lee, 9

CHICAGO, IL -- Police have charged Corey Morgan, 27, with first degree murder in the shooting death of 9-year-old Tyshawn Lee, officials announced during a news conference Friday.

Police Supt. Garry McCarthy said investigators say "at least" three people were involved with the incident. In addition to charges against Morgan, an arrest warrant has been issued for Kevin Edwards. Another man is currently in custody on unrelated charges.

McCarthy said Morgan is a documented gang member and convicted felon. Investigators had been questioning Morgan in the case. He was arrested on an unrelated gun charge and was released on bail earlier this week.

Around 4 p.m. on Nov. 2, Tyshawn was lured into an alley near West 80th Street and South Damen Avenue and executed, police said. He was shot in the head and suffered several graze wounds.

Tyshawn's family said he loved to play basketball and video games. A basketball was found in the alley near his body.

Authorities said the child was executed in retaliation for his father's gang ties in an ongoing fight between rival gangs. Pierre Stokes, Tyshawn's father, has denied those allegations.
