What characteristics would lead a provider to suspect domestic violence, child abuse, or elder abuse is taking place within a family?

The characteristics are:

- wounds that exist on the body. If the perpetrator is smart, they often placed the wound on area that could be covered by clothes (such as arms or bod)

- The negative reaction that the subject had simply because of the presence of another individual that supposed to be close to them.

- The way that subjects interact with other people outside close family/relation.
