Never noticed this before - the December 9, 1971 edition of the school paper had an article about an
abortion clinic in New York. Page 5 (right next to an advertisement for Wild Mountain Thyme).

That would explain so, so much, including Lynne's alleged talk the next day of a trip to New York, her distracted state of mind, her seeming indecision about her activities, the school's desire to list her as 18 and not 17, and the delay in presuming her missing.
Unfortunately, it would also provide potential motive for the father to harm her, perhaps especially if the father were not a student, but an adult. An adult would have additional motive and means to cause her to disappear if, for example, he was someone who was married, well or even prestigiously employed, had a vehicle, exerted greater influence over her than a student might, etc.
Consider A.I.'s now-less-mysterious
statement: "If there are people that disappeared to make Durst's life a little smoother, a little softer to navigate, I'm not surprised."
That fact would apply to anyone who was the father, of course. The FBI contacted D.V. at least twice in 2014 or 2015, and according to his own statement, never asked about Durst;
they asked whether D.V. himself remembered seeing Lynne in the store. Keep in mind that the store belonged to D.V. until at least the fall of 1971, in other words, weeks before Lynne's disappearance.
Rumors of Durst owning the store and the Ripton property are as-yet unproven by documentation, whereas D.V. is actually on-record, with zero doubt, as having owned both. The FBI questions D.V., and suddenly someone floats the (yet unproven) idea to the media that "a serial killer lived at 301 Robbins Crossroad."
D.V. claims Durst did not live there; A.I. claims Durst did.
Interesting.
