Whether the stellar (or not stellar) team searched that particular area or the family did multiple times, it still doesn't make sense to me that the body would not have been found sooner.
I realize that many searches were focused on areas south and east rather than north and/or west based on sightings and scent trails, and I realize that the SAR search "targeted" these other areas. I also realize that searchers, especially non-professional ones, may not have raised their eyes or looked in specific places with dense brush, but the idea that she could have been in someone's (albeit heavily wooded) "back yard" 3 blocks up from Sumac Ln for so long just doesn't make much sense unless you really think about it and suspend disbelief for a few moments.
I'm assuming that the approximate time of death can be established by an autopsy, but would only be precise enough to narrow to weeks rather than days (unless she is much more recently deceased than presumed). It is possible, but perhaps not probable, that Leanne was not yet deceased and/or not present off Fairview Circle when they performed the initial search of that area, not that it matters at this point unless there is some doubt as to whether suicide or foul play is the cause.
It is probably yet another example of bad reporting, but tonight's Herald Zeitung article contained a curiously written line: "Less than two weeks after she went missing, tips reportedly came in placing Bearden alive and well, walking around the Farm-to-Market Road 3009 area"... which almost implies that Leanne was seen on multiple days after her disappearance, strolling around the GR area.

I find that prospect unlikely, and being "alive and well, walking around (Garden Ridge)" is likely simply a clumsily worded reference to the 2-3 sightings along 3009 the day she went missing. Assuming the sightings were not discounted and some reports of the scent following her towards I-35 on 3009, it is possible that she did indeed walk in that direction that day, either in a (failed) attempt to leave town or to obtain supplies to carry out whatever her original plans may have been (suicide or otherwise).
But somehow she ended up back on Fairview Circle; when and how is still a good question.
