CHICAGO (CBS) -- Chicago Police Superintendent Garry McCarthy says they think they know what happened, they just need to prove it.
"We are going to close this case, there's no doubt in my mind," said McCarthy.
McCarthy says contrary to earlier reports, the baby's father was not changing the baby's diaper when the shooting happened.
"The baby was sitting in his lap in the driver's seat and the shooter came from the sidewalk over his right shoulder," said McCarthy.
