Limitation as to time of death. (1) A person is not deemed to have killed another if the death of that person does not take place within a year and a day of the cause of death. (2) Such period is reckoned inclusive of the day on which the last unlawful act contributing to the cause of death was done, and when the cause of death is an omission to observe or perform a duty, the period is reckoned inclusive of the day on which the omission ceased. (3) When the cause of death is in part an unlawful act and in part an omission to observe or perform a duty, the period is reckoned inclusive of the day on which the last unlawful act was done or the day on which the omission ceased, whichever is the later.
