Why would JL lie when he didn't even know the TV was planned on being repaired. He had no idea it might have been used as an alibi so had to reason to lie and pretend it was a crappy TV that you would never repair.
I do not believe Jeff ever mentioned the TV in any of his police interviews, which tells you it wasn’t meaningful to him in 2014 or 2015 in his third interview. The “TV alibi” theory likely didn’t even exist yet (or wasn’t public)… but by the time he testified, years later, he had gone through prosecution trial‑prep. Those meetings aren’t recorded or discoverable, and that’s where witnesses are walked through timelines, evidence, and the State’s theory.
If the prosecution believed the Best Buy appointment was suspicious (and they clearly did), then Jeff would have learned that before he ever took the stand in a trial‑prep meeting with the prosecutors. They would have asked pointed questions about the TV, and he would have given them all the details he later testified to. IMO, once Jeff understood the importance of the TV alibi, hindsight bias kicked in. People naturally reinterpret old memories through the lens of what they now believe matters.
The result is we got the story about watching the movie on the broken screen to establish the timeline, Wendi’s refusal of Jeff’s offer to purchase a TV, and Jeff’s interpretation that her refusal didn’t make sense because it was a “small dorm‑room” type display and wasn’t a big deal to him etc. He created a mental image for the jury that it was a cheap, small, disposable TV that he could have easily replaced for her, and that it made no sense she would refuse his offer. We got a lot of subjective framing to support the alibi theory... and her refusal to have Jeff replace it meant she needed it there for the ‘planned’ alibi.
During the trial, when Cappleman says something like “tell us when you first learned the TV was broken,” this is information they gathered in trial‑prep. His testimony conveniently supported the alibi narrative. To be fair to Jeff, rather than saying he lied, it’s possible his hindsight recollections were shaped by the narrative he came to believe… and if his description of a 55‑inch TV (assuming it was in fact 55-inches) was that far off, IMO, it’s fair to question how much of his other testimony was influenced the same way. It’s also fair to question whether his embellishments were purposeful or done subconsciously.
