Modern city/regional snow plows have sophisticated GPS technology in them, where dispatchers/controllers can track their every move. Controllers know exactly where their fleet is at any given time because of GPS. The CW chose not to corroborate Lucky's story by calling in a representative of the city/region to speak to this - or maybe they did interview them and realized Lucky was truthful.
Lucky also stated he had bright lighting all around his plow where it lit up the entire area, so it wouldn't have been dark for him. Workers remember snow storms, especially ones described as blizzard conditions. They talk about them for months and years later and they're able to recall strange things out of place when weather events happen because it's not the norm.
If that vehicle had been parked on the street, Lucky would have had to go around it with his plow, leaving a bank of snow far out in the middle of the road surrounding that truck. Since that was his last pass before LE arrived, that mound of snow should have still been in the roadway when they arrived. But it wasn't noted as standing out as far as I can tell.
When LE arrived around 06:00 (?), the first officer testified there was only a light dusting of snow on the body, even though people testified there was about 6 inches of snow that had fallen overnight. Maybe the women had dusted off some of the snow from his body when they arrived, but if the snow hadn't begun to fall until close to midnight like some stated, and 6 inches of snow fell on the ground before morning, then why wasn't there 6 inches of snow on top of JOK if he had been laying out there since 12:30sh.
MOO.
