Russell Bowlin's Family Was Involved in His Disappearance

One theory is that Russell Bowlin's own family was involved in his disappearance. The Bull in Family felt that they came to this theory too quickly, and then that influenced them looking into other theories. Some people think that their behaviour all the way throughout this case was just very, very suspicious. How can they be so sure as they are that Russell only had £10 in cash on him? His car only had 3.8 litres of petrol in it. Those are two very specific numbers, and two things that you wouldn't really know about your son,. you know? They're just so sure that someone else was involved, that they shut down every single other theory like that he ran away
