Karen. You need to look at British Newspapers Archive or the same records on Find My Past.
The accident is briefly reported in Sheffield Independent of 20th May 1920. The coroner's report is in Sheffield Daily Telegraph, also on 20th May 1920.

Hi Karen

I sent copies of those newspaper articles to your email address.
The email bounced back because your "mail box is full,and cannot accept messages".

Let me know if you want me to send the email again.

Hi Ann
Please if you could send them again that would be great. Hopefully it's sorted now. Thank you so much.
