Fifth victim in Chicago apartment shooting dies

A fifth person has died from wounds suffered in a shooting at an apartment building on Chicago's Northwest Side.

Police say a 67-year-old man went into a neighbour's apartment Saturday evening, fatally shooting four people as they ate dinner. They say the suspect then went to a unit on the floor above and shot another woman, who died of her injuries Sunday.

The suspected gunman has not yet been identified or charged as of Sunday afternoon.

He was taken into custody shortly after the shooting.

First Deputy Supt Antony Riccio says the man had a history of issues with his neighbours but investigators "don't know what set him off."
