Blue22, this is a bit OT from your post, forgive me--I didn't know how else to "tag" you. I posted something in prev. thread that I was wondering if you could shed some light on, as I think you said you owned the same car....
I was wondering about window tinting. It reduces the UV and thus the internal temp. Was wondering if this is a standard feature or maybe a custom feature of this car.
I've read that window tinting can reduce the internal temp. by anywhere from 15-70%+, depending on the level of tint and brand. Wondered if there's anything about this in the car specs or manual. Although he confessed wanting to know what temp was needed (!?), I think it would have been easy for him to forget about this feature of his vehicle!
My feeling is, if he searched what temp it takes to die, he might have miscalculated. For example, if the rule is 1 hr in 100 degrees (I honestly have no idea, and really don't want to search these specifics), but his window tinting decreased internal temp by 60% (for example), it could take 2.5 hours instead of 1. That's just an example. There's a million variables, obviously...
But the point is, in a tinted car, the temp would increase slower. So I think, if he arrived at 9:30, and went out at lunch time (could be anywhere from 11:45-2pm...), especially if it was on the earlier side, his child could have still been alive...and he couldn't have done his reveal as planned. Just a theory...
Again, sorry this is OT from yr post but I thought you may have some info and insight!
