THE CROYDON MURDERS 1929
By Tim Lambert
In 1928-29 three people were poisoned with arsenic in the south London suburb of Croydon. On the evening of 26 April 1928 after a meal 59 year old Edmund Duff fell ill and he died the next day 27 April. His death was attributed to natural causes.
Then on 14 February 1929 Edmund Duff's sister-in-law Valerie Sidney fell ill. She died on 16 February 1929. The last victim was Violet Sidney, Valerie's mother. She fell ill and died on 5 March 1929.
Violet Sidney was buried but soon people became suspicious and her body and that of her daughter Valerie were exhumed on 22 March 1929. Both contained arsenic. The body of Edmund Duff was later exhumed and was also found to contain arsenic. The police investigated but nobody was ever charged.
