On Nathaniel Sebastian's Facebook, he has a backhoe. It was shown with him on it. He also has not posted anything about his mothers disappearance. Yet has has posted once after the 17th. And has also posted several times before the 17th. On April 5th, 2017, Nathaniel posted on Facebook about how to asks for forgiveness. And then said the mailbox suffered. Leading one to believe that he used physical force on it. This seems to be an action caused by, a woman known as, Karen's father. Nathaniel has also posted on searching for a job. There is no more information regarding him procuring a job.
I believe that Nathaniel Sebastian and his mother, Susan Mayo had been arguing over his lack of working. It is plausible that he owed child support, and may owe back child support. The police, and Sebastian's own Facebook page, tells of him have a quick temper. As did his own mother. This coupled with both arguing and the child support/job, led to him hurting Susan Mayo. Sebastian is not shown to be careful. Judging from his lack of ability to spellcheck in his posts. Even the most obviously misspelled words, are not corrected. Which shows a lower level of intelligence. He has been shown to have a gun, make unknown. But, with his inability to easily spell out the rights words, leads me to believe he couldn't have used that gun. Or any gun for that matter. Nor any knife. It would require him to scrub down wherever he shot/stabbed Susan Mayo. His work would be sloppy, or not finely done. It is possible that he shoved her hard enough for her to hit her head. Him believing her dead, disposed of the body. Or picked up the nearest heavy object during their heated argument, and bludgeoned her to death. He had posted photos of odd nick knacks. Including two bronze door knockers, supposed from the 16th century. Susan Mayo may have told him to pick up his knacks off the counter, and he did just that. Sending her flying to floor, where he then realized his mistake. And then used the backhoe in his posted picture. Then buried her, somewhere in the yard. But, the ground would be soft, and the grave would be easily recognizable. So where her body is, unknown. After all this is Alabama, and there are several bodies of water all around.
