They were not locked inside the trailer. Other versions of this story have family picking people up. According to he local news at least 5 people were "picked up". That's the true disgrace here, nobody had to die, all they had to do was leave the truck. IF it was locked then ONE phone call before people started dying would have saved them all.

While the whole incident is abhorrent in the end who pays for the ones who live? The US taxpayer. You had Medevac helicopters which are 25K a flight PLUS the cost of trying to save these peoples lives. The bill will be substantial. In the end the US taxpayer pays for this.
