I'd be surprised if there weren't a larger-than-normal number of male volunteers to go look for her--at least initially.
This kind of "Horny Samaritan" situation isn't entirely unknown in rescue/recovery operations.

Evelyn Consuela Rosemann, 24
October 18, 1968
Nevada Fall (594 Feet)
After 3 days in Yosemite, Rosemann of San Francisco was found by 3 hikers on October 19, 200 feet from the base of Nevada Fall in suspicious and unique circumstances. Whether her death while solo hiking [emphasis in original] was due to an accident, suicide, or murder has not been determined. Rosemann had been raped pre- or postmortem, the latter more likely. It is not known for certain whether she went over the waterfall or the dry cliff.

Weirdly, when discovered by the three hikers, her body had already been moved for a significant distance from its point of impact. Investigators found traces of the corduroy material at least halfway to the base of the fall. Additionally, they discovered parts of her brain on a rock in the middle of a stream, fifty feet away. That Rosemann's clothes had been yanked almost off was also hard to explain. Yes, it could have happened in the river (had she been in the river). Or it could have been done by human hands. Far more bizarre, the pathologist's report noted that sexual intercourse had occurred either shortly before or, more like, after [italics original]her death--as hinted by the bloodless lacerations of her vagina. The latter strongly suggests someone had raped her mutilated corpse after her fall.
Hence the questions remain: Was she attacked prior to going over, maybe by a stalker and former client from the Bay Area [where Roseman worked as a massage therapist and topless waitress]? Had the attacker been rebuffed and then pushed her off the cliff and afterward raped her corpse? Or instead, after her fall--accidental or otherwise--had someone simply happened upon her corpse and had sex with it?
Consider that the autopsy report described "severe and tremendous traumatic injuries of the type ordinarily seen only in mountain climbing accidents or in train vs. auto collisions. The cause of death appears to be a massive head injury with avulsion of the brain." The type of individual who even COULD, to say nothing of WOULD, have sex with (I might debate the verb "rape" in a postmortem context) a corpse which has had its brain avulsed (splattered all over the place) would have to be way far out near a pointy end of the bell curve in a game of "Never Have I Ever." But it's not entirely impossible that a similar individual might live in the PNW, watch Fox News, and hear "missing naked 19 year old woman," and sign up to volunteer, whether hoping to find her alive or dead.
It's unlikely, of course. But it has happened (probably by chance encounter rather than design), so I thought it was worth sharing.
