The follow-up material adds one of the most important missing pressures in the case: Steve Horning and the question of who might eventually control the museums and related assets. Patsy reportedly became determined to keep Steve from ever controlling any part of her assets or the museum structure. A buy-sell agreement between Patsy and Sally used life-insurance policies so the survivor could buy out the other’s stock, but rising museum value and Sally’s cancer diagnosis made the arrangement more dangerous than it first appeared.
The same follow-up says Patsy and Sally were reportedly supposed to meet shortly after Patsy’s death to address this issue. If Sally died first, Steve could have ended up with controlling influence in the museum structure. That does not prove Steve killed Patsy. But it does show that the museum world contained a real internal motive field, not just background noise.
Patsy reportedly feared Steve could eventually gain influence over museum assets through existing arrangements.
Steve reportedly took two polygraphs: the first inconclusive, the second passed. That keeps suspicion alive without making it clean.
One reason investigators hesitated was that Steve reportedly attempted mouth-to-mouth and got green liquid in his mouth. But the obvious counter-question remained: if he were guilty, why was the bottle still there?
Steve reportedly said he moved a table with two plates from near Patsy’s bed, but others did not clearly confirm that detail, making it disputed.
A good juror does not need to decide Steve Horning is the killer. The harder question is whether Steve’s presence in the contest file makes the State’s clean focus on Robert Cox less secure. If the answer is yes, then Steve matters — even if he is never your final choice.
