Let's try to find some common ground to start with now and work our way out from there.
*I don't think there is anything, but a common female's robe/housecoat there for us to dwell on, IMO. It isn't rare or unusual in the design or the materials used to make it.
*The lack of blood stain or matter could be simple...she was in the robe, but was covered up with a blanket or something...so he just removed it. Or it was stained on the back of the robe and since we aren't seeing the site of the wound or exit, if there is one, and cannot conclusively say if it is matter or coagulation mixed within the hair. (I just watched Dr. Lee's re-inactment on testing his own blood for timed coagulation and it looks very similiar.) She could have been knocked in the head or anything. We don't know. Another thing is with the color of the robe in this photo, blood could have absorbed into the velour and not changed it dramatically from a poor quality photo standpoint. It is possible he redressed her or dressed her, but this would have disturbed the blood more, wouldn't it? So here we have our first set of unknowns, but we can agree she is deceased by some unknown cause. (Also meaning the OSBI intentionally mislead the public and the McClaine County Sheriff's Dept. didn't get the memo. Great detective work, KatK!)
*However, I haven't found a single drop on the bedding or the wood. has anyone else seen any indication of that? (I believe the bright pink on the left bottom corner is a pink flower with small petals such as a hydrangia or similar. It seems to have flecks of white mixed in to resemble such so would be part of the overall piece of the pattern on the cloth and not splatter.) So to think she was put there afterward would be a logical assumption meaning staged.
*Docwho3 might have a good point about it being somewhat artistic, but I am not sure we could begin to apply that to such a photo or a profile of this perp. He is a sick, demented person to do this and photograph it in the first place. I do think it is a trophy of some kind in his warped mind and I think maybe we could agree on this point. It could be a "hit photo" for proof, but the ones I have heard about are taken with the gore intact and not staged afterward. (Still, this all really gives me cold chills about this poor girl and how coldblooded, methodical, and really evil he is.)
*Other things point to staging as she must have been turned or posed to this position because of the blood flow towards the right side of the face then turning towards the chin area. He at least moved her head facing the other way, but could have been smeared toward the chin and the smears on her arm also indicate he moved her, IMO. I still see a considerable bruise/discoloration on her arm from the elbow up towards the hand and coming around the muscle area. It looks like it could be from someone grabbing her with lots of pressure from the front, but it could be the result of blood pooling in the area if the arm were in a down position for a time after her death. (If I have listened to Dr. Lee's, Dr. Perper's and other forensic explanations carefully.)
*I noticed the white cord like or plastic long piece in the first revised photo because it was out of place in her hair. It would make sense it once restrained her where we once figured it was used to strangle her and now we have the other photo which seems to negate that. I am not seeing where there are any visible ligature marks either on her wrist or her neck area tho, so is it possible it was around her ankles at some point? Then it would be reasonable for us to agree she wasn't with him of her own free will and was being restrained indicating an abduction at some point.
*The photo does look "incomplete" like LE cropped it or the perp did.
**These I think are all points we can agree on, yes? (OK, I know some won't agree about the robe or even the possible timing *80s/90s. <shrugs> so we won't include those for now.)
Female.
Reddish/Auburn hair.
Late teens/mid 20s.
Unknown cause of death.
Unknown crime scene.
Staged/posed/cropped scene.
Photo for trophy.
Abducted.
Photo found outside a remote gas station near Purcell, OK. 4 + miles from Interstate 35.
These points can give a direction towards known perps with similiar MOs to research.
Franklin D. Lloyd serving currently on death row so could not have been at the scene where photo was found during the time frame. Was known to take photos then place them between the gas tank and frame of car underneath tho.
Tara Calico's abductor: Unknown. Left various photos to be found: One of girl and boy in duct tape and bound. Other photos which I don't think were ever released, but LE has recovered from a gas station and residential construction site and are believed to be Tara. (Were there other sites and photos released?)
Do we know of any more cases similiar to this?
