We do not know if Kenneth went to Columbus to work every day, but if he did, he would have to leave his camper early in the AM to get there or to a job site......supposedly he planned on an overnight guest and working on cars at 5:30 am.............so it sounds like he did not plan to go to work that day. But if the early am car work is not true, then whoever killed him had to catch him at home before he left for work. JMO
Sounds like he didn't plan on going to work but everyone didn't necessarily know that and could have assumed he was there.
