There seems to be confusion in the way this was reported - at it first appeared that this was the first time she jogged alone, but then from what I've read - she'd been doing it alone ever since her father's back injury that resulted in his disability. But, never clarified just how long that was - days, weeks, months?
ETA: so many little "Colombo-like" details we are missing in this case, such as the above as well as -
>did she normally jog back over the same path she went out on, and if so did attack happen as she ran out, or returned back.
>did she normally text and listen to music at same time.
>did she keep one ear bud out to hear surroundings.
>when she texted did she slow down or stop.
>how fast a jogger/runner was she.
>size of rock used.
>was it determined where the rock was taken from, at the scene of someplace else.
>was there any sign in the weeds of a place where someone was hiding out, such as a small clearing and path to it.
>did she keep her hair up or down (pony tail) when jogging.
>how well was crime scene preserved.
>any foot prints, bike/tire marks.
>what do overview photos show of the area.
>did she break teeth biting assailant.
>no mention of DNA under her finger nails.
>what kind of DNA was found on her - some types of DNA can reveal certain traits.
>how long had she been doing this jog alone for (days, weeks, etc.).
