Ok I found out more, they were on their way home not sure how far from where they were in FL. But my dad told J to pull over at the next place because he had to use the bathroom. They stopped, grabbed a few things and went back to the truck. They got in and J just fell right over onto my fathers lap, he couldn't talk or move his arm. Dad couldn't move because J is a big man. He's blaming himself some, because he thinks he could have done more, he was limited in what he could do at all. It was most likely a Heart Attack. My dad just wants to come home but he has to wait with the Semi til the boss and another person gets there tomorrow at 4pm. So keep the prayers and thougths up with him. I know its hard on him especially being alone and so far from home.

PTL that my dad needed to pull over, it could have happened while doing 60 down the HWY.
