Which of the following might indicate a case of domestic violence during patrol?

Visible injuries and emotional distress are strong indicators of potential domestic violence during patrol. When law enforcement officers observe physical signs of injury, such as bruises or cuts, coupled with signs of emotional distress—like anxiety, fear, or withdrawal—it suggests that an individual may be experiencing a violent situation at home. These visible markers can prompt officers to investigate further, assess the safety of the person affected, and take appropriate action to ensure their protection.

The other options, while they may suggest issues that need to be addressed, do not directly indicate domestic violence. Frequent calls about loud noise might relate to disturbances but do not necessarily confirm violence is occurring within the home. Likewise, reports of missing persons could involve a variety of circumstances unrelated to domestic violence. Frequent requests for welfare checks could suggest ongoing concerns for an individual's safety or well-being, but without visible signs of injury or emotional distress, they do not directly indicate a domestic violence situation.
