I just find it odd, though, that DS was supposed to spend the night and work on cars at 5:30 the next morning. I mean, how long could he have worked on cars if he had to leave for Columbus to work? Seems like DS would have thought to check on him, being a Rhoden and all.
There are a lot more people who should have checked on Kenneth before his cousin did. I suspect one of them called DS and asked him to check on KR when they couldn't get in touch with him during the 1-2 hr period from when they learned of the deaths until DS arrived at his home. The people you would expect to being beating a path to get to him if he wasn't answering his phone are listed in his obituary:
Along with his mother Geneva, Kenneth is survived by a son Luke C. Rhoden, 2 daughters; Tajianna (Michael) Mead and Kendra A. Rhoden, grandchildren Rayn, Trey and Hope Mead, and Hayden Rhoden, 2 brothers; Brady and Tony Rhoden, 4 sisters; Norma Thomas, Wilma McCoy, Brenda (Dave) Weisel and Teresa (Dan) Grebing, a very dear couple to his heart Delbert and Violet Rigsby, along with a host of nieces, nephews, cousins, friends and his sidekick Brett Hatfield!
