June was Nevill's first option.
June was the nearest available adult.
Natural reaction for Nevill to wake June. Rather than ring Bamber's AM at 3.10am.
June was 30 yards away.
June was awake or likely to wake from Sheila's outburst anyway.
June was a light sleeper. So likely to wake anyway.
It was June's house which gives her some authotity.
June was Sheila's mother. Sheila more likely to respect her than Bamber.
June was Sheila's mother. Will have more experience of calming down Sheila than Bamber.
June was financially supporting Sheila's life in London. Sheila likely to be less hostile.
June had invited Sheila to WHF. Sheila likely to be grateful & less hostile.
No evidence Bamber got on better with Sheila than June did.
June was as strong as Sheila.
June could protect the twins when awake.
Waking June would prevent her getting shot 5 times in bed.
Nevill would not have to repeatedly ring Bamber's AM at 3.10am.
Nevill would not have to wait hours for Bamber to perhaps turn up.
June was already in a house where Sheila was apparently having a psychotic outburst. No point also trying to get Bamber inside.
June assisting would mean the police or Bamber would not have to be called.
June would not call the police. Unless Nevill told her to. Bamber said Nevill liked to keep things private. Ringing Bamber risked Bamber calling the police.
Nevill ringing Bamber's AM while June continues sleeping means Sheila is not being monitored. Better to wake June.
Ringing Bamber's AM while June sleeps puts the twins in danger.
June will not be upset if Nevill wakes her for assistance. Her daughter needed calming down.
Waking June is putting her in less danger than her continuing to sleep.
Nothing to lose in getting June to assist. If Nevill is having difficultly himself.
If June & Nevill still could not calm down Sheila, at least June was up & awake. Rather than a sitting duck.
Bamber said himself him & Sheila did not like each other. Nevill would know this.
Bamber has said since conviction he did not understand Sheila's illness. Nevill would know this.
June was available instantly.
If June was only of minimal help, that is better than the zero help Bamber gave.
