Robert Raymond Cook


Robert Raymond Cook was a Canadian mass murderer, convicted for the killing of his father Raymond Cook in Stettler, Alberta, in June 1959. Cook murdered his family, including his father, step-mother, and five half-siblings at their home in Stettler, but was only charged for his father's murder, for which he was convicted and sentenced to death.
Cook was executed in 1960, the last man to be executed by the province of Alberta.

Murders and execution

On 28 June 1959, police discovered Raymond Cook, his wife Daisy Cook and their 5 children shot and bludgeoned to death in the grease pit of their garage in Stettler, Alberta. Raymond Cook's son by his first marriage, Robert Cook, had been arrested in Stettler the day before and charged with obtaining goods under false pretenses, after he had traded the family's 1958 Chevrolet station wagon for a '59 Impala convertible. Robert was arrested for the murders, and despite being implicated in the deaths of all of his family members, was only charged with the murder of his father in order to speed up the trial process.
At just after midnight on July 11, 1959, Cook escaped from the Ponoka Mental Institution he was detained in, for a psychiatric assessment, after he had been denied permission to attend the funerals of the family members he had killed, and was found several days later hiding at a pig farm near Bashaw, Alberta. It took two trials and just under 16 months for Cook to be convicted of murder, where he maintained his innocence up until his execution. Cook was sent to the gallows at Fort Saskatchewan Provincial Gaol at midnight, November 14, 1960, and pronounced dead at 12:19AM on November 15, 1960. The case has been the subject of several books and two plays.
