A quick definition of accidental death:

Accidental death is when someone dies because of an unexpected event that was not planned or meant to happen. It is different from natural death, which happens because of old age or sickness. Brain death is when someone's body stops working and they cannot respond to anything around them. Civil death is when someone loses their rights because of a serious crime or by joining a religious group. Compensable death is when someone dies while working and their family gets money to help them. Instantaneous death is when someone dies right away after an injury, and immediate death is when they die soon after. Legal death can mean different things, like brain death or when a company goes bankrupt. Presumptive death is when someone is missing for a long time and is assumed to be dead. Simultaneous death is when two or more people die at the same time and it's hard to tell who died first. Violent death is when someone dies because of violence, like a gunshot or explosion. A death case is a legal case where someone may be sentenced to death, and a death benefit is money given to someone's family after they die.
