The real question you need to ask these days is was the electron every really there at all.
See here we even took a movie of it

The more QM view is thus:
(
http://en.wikipedia.org/wiki/Virtual_particle)
A virtual particle is one that does not precisely obey the m2c4 = E2 - p2c2 relationship for a short time. In other words, its kinetic energy may not have the usual relationship to velocity–indeed, it can be negative. The probability amplitude for it to exist tends to be canceled out by destructive interference over longer distances and times. A virtual particle can be considered a manifestation of quantum tunnelling. The range of forces carried by virtual particles is limited by the uncertainty principle, which regards energy and time as conjugate variables; thus virtual particles of larger mass have more limited range.
In other words an electron is a thing that you see because of quantum tunneling into your physical world (

The illustration shows the idea of how it works.
Your very physical world is built of very weird bricks that sort of appear not to be there but are nothing more than an illussion.
