I don’t think more than one person need be involved...but it does seem strange that the right truck has never been identified in a year’s time. The truck not being found is amazing to me...
Although I've been a member for 3 yrs, I've only posted 4 or 5 times (to a different forum/thread, all in the last week or so), so I'm still learning the ropes.
I have two theories on this case. The first involves the husband (only because the odds are high statically). The second involves EB's job as a data analyst, and the nature of the services her employer (the corporation) provides to its clients in the oil and gas industry. I thought I'd mention the second theory here, as it hasn't really been addressed yet in the thread.
From its website, it appears that EB's employer is a large corporation that provides systems and services to "enterprise clients" in the oil and gas industry - an industry in which enormous amounts of money are often invested and at stake.
Under the broad definition of asset management, the corporation does things like: inspect tank farms, transmission pipelines, and gas distribution systems. They assure compliance with gov't and industry regulations, determine the safety and integrity of assets and systems, evaluate system performance and production, and determine asset and system market values (I assume by doing appraisals, calculating depreciation, life cycles, doing risk assessments, evaluating market conditions, etc.). I assume that the end results of their work are then published in some kind of report and presented to the client, a gov't entity, potential investors, or other parties.
Obviously, to an enterprise client in the oil and gas industry, there could be significant positive or negative implications which might result from such a report. Having such power over large market value enterprise clients with so much at stake might create an environment where corruption could occur - an environment in which the corporation, the enterprise clients, various gov't oversight entities, and investors might all need to be diligent to guard against crimes like extortion and bribery.
An enterprise client might be tempted to try to influence an employee of the corporation (say, to alter or suppress report results), or an employee of the corporation might be tempted to try to profit from altering or suppressing report results. Likewise, an investor or representative of the gov't might be tempted to influence outcomes for one reason or another (I know, say it ain't so!).
Given the above, I think it's worth considering whether the motive behind EB's murder could've been related to her job. It certainly would be possible that someone associated with the corporation, an enterprise client, or an investor might have wanted her dead. In conversations during the course of regular business, such a person might have been able to acquire advanced knowledge of Elizabeth's plans to be off that day, as well as her plan to hold a garage sale. In the same way they might have come to know her husband's work schedule.
Re: other/certain aspects of the crime:
I think EB was specifically targeted (I don't think this was a random shooter thing like they had not too long ago in Tampa). If it was a hit man commissioned by the husband, I think police would have probably solved the crime by now.
I think the suspect was a man dressed as a woman (this based on height, gait, right arm/hand strength, and familiarity with a handgun (the shooter may have even killed someone in this manner before). Re: the "experienced or trained shooter" discussion, I don't think many armed robbers or hit men (assuming such a person is involved) utilize a two-handed grip and self-defense stance in the commission of their crimes.
I think that if the murder was work related, it is likely that a hit man was utilized, possibly one from a gang operating on one or both sides of the border. The suspect might reside in Mexico, or even be in the US illegally (and as such might not have a DL, a record, or be listed in LE print and DNA databases). The black truck also fits this scenario, being of a type often utilized off-road, on ranches, and on back roads. The truck could have come from (and returned) across the border, or it could be a hidden, unregistered, or re-plated vehicle belonging to a gang operating in TX or the southwestern US.
