I had a couple of accidental deaths in Peckham/Camberwell to look into.
The first was in 1920, my mother's brother died after a lift accident at work at the age of 15. All I knew was the quarter in which the death was registered. I rang the South London Press, which covers that area, they confirmed they did cover Camberwell at the time of the accident. I made an appointment, went to their office and they had all the copies for that year ready for me to look through. When I found the article the lady very kindly photocopied the appropriate page for me.
The second one was my grandmother who had been killed in a road accident two days before christmas in 1944 in Peckham. This time I went to Southwark Local Studies Library, they found the films with the local papers for that period which I went through. Again when I found the correct article, they photocopied the page for me.
I think the local papers of the time were South London Press and South London Observer.
Good luck
