Ages ago now, but IIRC, there was a woman, a park ranger, who was familiar with the area, who was interviewed a number of times on MSM, on anniversaries of this young couple's brutal murder, who were just back for their first week of school. It seemed like they were trying to get in their car to get away when they were gunned down. David was shot first. He had gone there in the past to hangout on his own. It was his place to relax, to watch sunsets, IIRC, from MSM reports. There's a summer camp nearby too that would have been empty, at the time.
