Person Of Interest Being Questioned In Chicago Cabbie Murder: Police

(CBS) -- A person of interest is being questioned in the shooting death of a Chicago cab driver earlier this week, Chicago police said Thursday.

No charges had been filed, Chicago Police News Affairs said. A news conference was planned for Friday morning.

Kamil Shamji, 59, was found in his Flash cab Monday morning behind the Sulzer Regional Library in Lincoln Square, in the 4400 block of North Lincoln Avenue. He died of a gunshot wound to the head.

Friend Sohail Ghaziani called Shamji "a hell of a nice guy" and says he would sometimes let riders off the hook if they told him they had misplaced their money.

Shamji, a widower for the last 15 years, drove a cab to support his two daughters.
