I don’t think she did it out personal greed (except perhaps greed for publicity) - I think she believed she would probably make the tech work and just never got there. But regardless of the reason, investors are out a ton of money as a direct result of material misrepresentations. You cannot “fake it ‘til you make it” at least where investors are concerned.
Because of the amount of money involved, these two defendants are looking at a stiff sentence. The federal sentencing guidelines would easily put them at the maximum (20 years), though they may get something like 10-12 years if they take a plea early in the process and don’t make prosecutors work too hard to prepare for trial. This will not be a Martha Stewart type of sentence.
It’s a sad day for everyone involved.
