A person who knows or reasonably should know that a person is an elder or dependent adult and who, under circumstances or conditions likely to produce great bodily harm or death, willfully causes or permits any elder or dependent adult to suffer, or inflicts thereon unjustifiable physical pain or mental suffering, or having the care or custody of any elder or dependent adult, willfully causes or permits the person or health of the elder or dependent adult to be injured, or willfully causes or permits the elder or dependent adult to be placed in a situation in which his or her person or health is endangered
Elder abuse or elder endangerment usually involves caretakers, but that's not necessary under California law.
Thank you.
