The claim from supporters is it was Sheila making the call at 6.09am. No one seeing her do this through the kitchen window.
The phone call was after Sheila had -
Fired 26 bullets.
Re loaded twice.
Chambered twice.
Breached twice.
Fought Nevill.
Postioned Nevill onto a coal scuttle.
Burnt Nevill's back.
Wrote a long suicide note.
Got the bible.
Read the bible.
Had a shower.
Changed.
Supporters could have said it was either Nevill or Sheila making the call. Either way it would make Bamber innocent. However Nevill being alive for 2 hours 21 minutes after the police arrived & not letting the police know is not realistic.
It is of course much more realistic Sheila would stay alive & then dial 999 at 6.09am.
