We need to remember. That when people are paying out of their own pocket for treatment from a so called specialist. They want results without getting milked for all of their money.
Now once all of their money is gone while still suffering; Them or their loved ones would start to look at the specialist as a snake oil scam. Jmo
No rape. No robbery. Yelling taking place. YouTube videos promoting her revolutionary cures.
Tells me that a patient or loved one of a patient was not happy with the results and the drainage of the patient funds. Jmo
Anything is possible, especially given that most of what we think we know about the case, even the hammer, hasn't come from LE. The shouting isn't known to have come from the Sievers's house or to have been directed at the victim--could easily have been one perp to another.
Patients seem unlikely murderers, though, for a number of reasons. First, with the possible exception of transgender patients, most people looking for a holistic doctor and willing to pay out of pocket are older, at least relatively well-to-do folks. Older, well-to-do folks, despite Hollywood, don't tend to be homicidal. Also, many of her patients had probably already been disappointed by conventional medicine, so they weren't likely expecting miracles, just something better than what they seen before. Many seemed quite happy with what they were getting, including patients who posted comments on Sievers's memorial page saying they'd looked for a doctor like her for years and were unlikely to find another. Conventional medicine, on the other hand, killed 60,000 people with Vioxx alone, and I doubt a single prescriber of Vioxx was murdered or even sued (Merck itself paid out settlements of roughly $5 billion as just a normal cost of doing business). Second, very few patients, especially disgruntled former patients, would have known anything about the family's travel schedule, alarm system, etc.
By the way, here's a lovely story about the origins of snake oil (seems the original Chinese product, an omega-3 fatty acid just like today's fish oil, actually worked):
