Given that the RC and his girlfriend are self-proclaimed animal lovers, I wonder whether there may be some truth to this. That said, this is the same source that reported "gruesome animal experiments", so you have to remain skeptical.
Research involving animals is regulated extremely tightly, almost to the point where it can become quite difficult to plan and carry out experiments. A sad fact of research is that many mice are sacrificed as part of experiments, but it is safe to say that in my experience, while they are alive, they are treated with the upmost respect.
I would be very surprised if Annie Le, being relatively new to research, would be working outside established protocols. Rather, I imagine she would be erring on the side of caution.
