Lots of varying posts? A couple of points ....
As a parent two runners who have done a lot of training (one is running 22 miles now), run in countless events and are running the LA Marathon in two weeks, I can say it is 100% incorrect that it is "common for runners pass out or faint". If this happens to anyone, find a doctor quick! Seeing someone carrying anyone on a trail would be a huge red flag to other hikers or runners.
Not sure how we digressed to Lake Elsinore? Lake Elsinore is a relatively large (So CA standards) shallow lake. This lake varies greatly in water level over the years (more so than Hodges). As some have said, the residencial and commercial areas around the lake are growing. But, there is still many miles of open space and lake to hide a "needle" - making it rather impossible to find.
The Lake Elsinore demographics is lower than So CA average. As it has been pointed out, there are 99% more RSO, including JAG, and illegals in the Lake Elsinore area than around the Lake Hodges neighborhoods. Which is why, in my opinion, Chelsea's neighbors (and parents) are pissed a RSO was living, hidden, unregistered, in theirs.
If JAG is responsible for other disappearances, I believe they may need help in locating the missing. Their are just too many places to bury someone - and we do know he buries.
