The NYPD notified Hazmat and Department of Health to investigate if the funeral home was in compliance with New York state guidelines.
The funeral home was later cited for failing to control the odors. The home was able to obtain a larger, refrigerated truck later in the day, the official said.
Workers suited up in protective gear could be seen in the afternoon transferring bodies into the refrigerated truck.
Police closed the streets for crowd control and for health purposes.
When a call was made to the funeral home, a person on the other end picked up and then hung up. Subsequent calls went to voicemail, which was full.
Brooklyn Borough President Eric Adams went to the scene on Wednesday evening. He told the Daily News, "While this situation is under investigation, we should not have what we have right now, with trucks lining the streets filled with bodies."
He said “it was people who walked by who saw some leakage and detected an odor coming from a truck.”
