It won’t be intent. The article says that it’s involuntary manslaughter at issue. Probably negligence.

Involuntary manslaughter is the killing of a human being without intent of doing so, either expressed or implied. It is distinguished from voluntary manslaughter by the absence of intention. It is normally divided into two categories, constructive manslaughter and criminally negligent manslaughter.

Criminally negligent manslaughter is variously referred to as criminally negligent homicide in the United States, and gross negligence manslaughter in England and Wales. In Scotland and some Commonwealth of Nations jurisdictions the offence of culpable homicide might apply.

It occurs where death results from serious negligence, or, in some jurisdictions, serious recklessness. A high degree of negligence is required to warrant criminal liability. A related concept is that of willful blindness, which is where a defendant intentionally puts themselves in a position where they will be unaware of facts which would render them liable.

Criminally negligent manslaughter occurs where there is an omission to act when there is a duty to do so, or a failure to perform a duty owed, which leads to a death. The existence of the duty is essential because the law does not impose criminal liability for a failure to act unless a specific duty is owed to the victim. It is most common in the case of professionals who are grossly negligent in the course of their employment. An example is where a doctor fails to notice a patient’s oxygen supply has disconnected and the patient dies (R v Adomako and R v Perreau). Another example could be leaving a child locked in a car on a hot day.
