Yes, I am betting that is a typo by NBC, and that the deceased is 49.
Here's a site that runs press releases, raw, from the 77th Pct:
On Sunday, October 6, 2013 at approximately 1744 hours police responded to a report of a male shot in front of 1117 St. Mark's Avenue. Upon arrival, officers located a male black 49 years old, seated in a vehicle unconscious and unresponsive with multiple gunshot wounds to the torso. EMS also responded and transported the male to Interfaith Hospital, where he was pronounced DOA. No arrests have been made. Identity of the victim is pending proper family notification. An investigation is ongoing
The RNN feed used by Gothamist does not verify its information. Hence, if the ambulance communicates to the ER that they were on route with a 30 y/o, that's how it first appears.
Ditto the location of the car that the man was found in. The address has slightly changed from the initial report, as information becomes clear.
This shooting falls within the catchment area of SOS Crown Heights, an organization working to reduce gun violence.
The last shooting incident in the S.O.S. catchment area was on September 5th, 2013.
