When I looked over the timeline I noticed that we rarely know Steven's whereabouts at night. From about 12/8 or 12/9 until the time he disappeared.With the exception of his neighbor,John, who saw him last at about 10:30pm, as Steven was leaving his house.
I think he could have been gigging as a roadie/advance guy for a band.He had just done two roadie jobs for Dorsey. I wonder if the driving around could have been connected to this ? If he was doing advance work for a band, he would have needed to use his own vehicle. The reason he didn't mention it might be that he didn't think his family would be thrilled ? Looking at a map, could a band have played in,say, Provo, and then he drove back, buying fast food first in Springville,then in Nephi ? Is Provo a college town ?
That last night, the band could have been playing in the Vegas area. It does explain the late hour that he set out that Saturday night ? I wonder if he was going to get paid in Henderson ?
For someoe who's into music, this would have seemed like a great deal.He could have hooked up either through Craigslist, or someone he actually met when he worked as a roadie. JMO.... which is not worth much.
