UMPD at Corolla Crash? So What?

Assuming that Officer Ruddock was persuaded or pressured by someone else, probably a police officer, into letting a drunk Maura Murray leave the scene of the Corolla crash, how does that fit in with her disappearance?

Surely, investigators such as Lt. Scarinza and the FBI must have learned Maura was almost certainly drunk when she crashed the Corolla. And they must have likewise learned of any possible presence of an officer other than Ruddock at the Corolla crash scene. And/or the purported presence of a UMPD cadet.

Seems likely that detectives viewed Maura's apparent impairment, along with the alleged/possible presence of UMPD, or at least the possible presence of a UMPD cadet (as reported by Lance Reenstierna and Tim Pilleri in their Missing Maura Murray podcast, Episode 22), as unrelated to Maura’s disappearance.

But this belief seems based on two assumptions commonly held immediately after Maura’s disappearance: 1) that the Saturn crash occurred in Haverhill NH and therefore the Saturn’s body damage was sustained at the Weathered Barn Curve (WBC) as indicated in Sgt. Cecil Smith’s report, and 2) that Maura Murray was in fact the Saturn’s driver at the WBC.

Both assumptions have since been shown deficient.
