Police Commissioner Charles Ramsey says there are a lot of unanswered questions.

“There’s no gun on the scene, there’s no evidence that the shot came from outside, it’s an indoor scene.”

Ramsey says the boy’s parents were both at home and are being questioned. He was confident detectives will be able to identify the shooter.

“Any shooting or homicide is tragic, but it’s even more tragic when it’s a youngster. The child hadn’t even started to live yet, basically defenseless, and they wind up dead. That’s why it’s important we find out who’s responsible as quickly as possible,” Ramsey explained.

No suspects have been identified.
