Murder charges have been filed against a Chicago man in the death of a 9-year-old who police say was lured from a playground and shot in the head because of his father's gang ties.

Chicago police spokesman Anthony Guglielmi says charges were filed late Monday against 22-year-old Dwight Boone-Doty in the November death of Tyshawn Lee.

A spokeswoman for the Cook County state's attorney's office couldn't immediately be reached for further comment.

Guglielmi says Boone-Doty was being held on unrelated gun charges when follow-up investigations connected him with Tyshawn's death. It wasn't immediately clear if Boone-Doty had an attorney who could comment on his behalf.

Police say Tyshawn was targeted because of his father's gang ties and a series of gang shootings in Chicago's Auburn Gresham neighborhood.

Another man is also charged with murder in the killing.
