chosen.content: I have heard of cases where poison was intentionally administered over a prolonged period of time in order to cause someone’s death. The most famous example is probably that of Maria Marten, who was murdered in 1827 by her lover, Captain John Marten. Maria's body was discovered 5 months after she had disappeared; the investigation of the time found no suspicious evidence in the house, however when her lover's excrement was examined, arsenic was found in the contents, confirming that it had been administered slowly over a long period. Another similar example was the case of Ruth Ellis in 1955, who was executed in the United Kingdom after being convicted of killing her abusive boyfriend, David Blakely. It was also confirmed that he had administered arsenic to her slowly over a period of time, resulting in her death.

rejected.content: Yes, I have heard of a number of cases where murderers have chosen to slowly kill their victims through cumulative poisoning. The most famous case is that of Dmitri Aleksandrovich Karamyshin, who was convicted of killing three people with ricin over a seven-year period in Russia in the 1990s. This method of murder was used more recently by Curtis Posey, who was convicted of murdering his wife with poison in North Carolina in 2014. Other known cases include that of George Taylor in the UK in 2012, and Peter Falus in Hungary in 2011.
