22yr-old Ada Ocha Ntu aka ‘Esther Johnson’ and her lover Mark Hall in Lagos in the 50’s.
She murdered Hall in 1953 in a savage attack with a pair of scissors. Hall was a Colonial Railway worker and apparently she had killed him because he had returned from a home leave in England to tell her that he had married an English bride and had used the £400 Johnson had lent him to buy a taxi for his new bride so that she could start a business. Johnson was tried and convicted in 1956 and sentenced to death.
She remained on ‘Death row’ in Broad Street Prison(now Freedom Park) Lagos. Her sentence was later commuted to life imprisonment. In 1961, on the first anniversary of Nigeria’s independence, Governor-General Nnamdi Azikiwe pardoned Esther Johnson “in the name of the Queen.” The press celebrated the decision, and Johnson was released from jail.
