The body of Charlotte Christodoulou, 23, was found in the doorway of Harlescott Junior School in Shrewsbury, Shropshire, on 4 January this year.
And an inquest heard how Ms Christodoulou had gone into the grounds with Jamie Lloyd-Butler, 33, to take a shortcut to a friend’s house but was unable to scale the 10ft perimeter fence because she was too drunk.
She later died of hypothermia.
Mr Lloyd-Butler, from Harlescott, managed to scale the fence but denied he had left his friend to die.
‘I wouldn’t just leave her there,’ he said.
