SECURITY CAMERA AT PRAVA STONE WORKS: 18-21 130th St. in Flushing Queens

The security camera at Prava Stone Works  records 24/7 and is located exactly in front of the location where Sunny Sheu was found in a coma having suffered "blunt force trauma to the head with skull fractures and brain injuries"

But according to retired NYPD Detective Joe Mazzilli, who spoke to the owners of Prava Stone Works, the video data of that day have been erased and the NYPD never requested to see them.
