The latest on the arrest of a suspect in the killing of a 9-year-old Chicago boy who police say was lured into an alley and shot in the head as part of an ongoing gang fight (all times local):

4 p.m.

Investigators say a Chicago man suspected in the fatal shooting of a 9-year-old boy went looking for targets after his brother was killed during a months-long gang feud.

Prosecutors alleged Friday that 27-year-old Corey Morgan was among three gang members who lured Tyshawn Lee from a playground near his grandmother's home on Nov. 2, then shot the boy in the head in an alley.

Morgan's attorney says his client "absolutely denies" being involved.

Prosecutors say Morgan was intent on settling the score after an October shooting killed his brother and injured his mother.

Investigators say Morgan and two other men spotted Tyshawn in a play lot, and one of them approached the boy, dribbled his basketball and handed it to the boy before leading him into the alley.

Morgan is being held without bond on a first-degree murder charge.

Chicago Police say a 27-year-old man has been arrested and charged with first-degree murder in the fatal shooting this month of a 9-year-old boy on the city's South Side.

Police Superintendent Garry McCarthy said at a news conference Friday that Corey Morgan of Chicago is in custody. He says the boy was killed as part of a dispute between warring gangs, and he pledged to obliterate the gangs.

The victim, Tyshawn Lee, was gunned down Nov. 2 in what police say was a targeted shooting.
