Actually this is a good example of availability heuristic.

There's absolutely nothing whatsoever that is suspicious about this woman, but since you have this conspiracy "available" in consciousness, you can immediately recall it and connect her to it.

It's like if the news reported a terrible elevator accident, people would vastly overestimate the possibility of dying in an elevator accident, because you were thinking about it so much.

This is also why people may be surprised that lightening still kills more Americans every year than terrorists.

Availability heuristic From Wikipedia, The availability heuristic is a mental shortcut that relies on immediate examples that come to a given person's mind when evaluating a specific topic, concept, method or decision. The availability heuristic operates on the notion that if something can be recalled, it must be important, or at least more important than alternative solutions which are not as readily recalled.Subsequently, under the availability heuristic, people tend to heavily weigh their judgments toward more recent information, making new opinions biased toward that latest news.

The availability of consequences associated with an action is positively related to perceptions of the magnitude of the consequences of that action. In other words, the easier it is to recall the consequences of something the greater those consequences are often perceived to be. Most notably, people often rely on the content of their recall if its implications are not called into question by the difficulty that they experience in bringing the relevant material to mind.
