New York City’s Department of Investigation says a 911 dispatcher’s oversight caused a four-minute lag in processing calls to rush an ambulance to the scene of a car crash where a 4-year-old girl was crushed to death.

Thursday’s report echoes what the Fire Department has said about the case of Ariel Russo.

The investigation department report says police radio calls for an ambulance were promptly routed to the emergency medical system. But it says the dispatcher didn’t act on the information for four minutes, then took a break. A colleague relieved her and saw the call.

The dispatcher has said the call wasn’t in the system or she didn’t see it.

The report notes that a passing firefighter and a flagged-down ambulance attended to Ariel before the dispatched ambulance arrived.
