The truck found burning underneath an overpass was in LaPorte, which is not even near San Jacinto County, so that wasn't his truck.
Depending on where the truck was left, the fire may or may not have been reported. There are a lot of people in Texas, but there are also a lot of non-populated areas. It could've been days before anyone noticed it depending on where it was. And, at least in my part of Texas, people tend to "mind their own business." Even if someone had seen the truck earlier, they likely wouldn't report it because it wasn't their business.
