What must an officer determine to take a minor into limited custody without a warrant?

To take a minor into limited custody without a warrant, it is essential for the officer to ascertain that the minor's safety is at risk due to parental control issues. This criterion recognizes the importance of prioritizing the well-being of the minor, particularly in situations where their living conditions or parental guidance may pose immediate dangers. Parental control issues can lead to an environment that is harmful or neglectful, necessitating intervention by law enforcement to protect the minor.

In this context, the other options focus on actions or behaviors of the minor, such as engaging in criminal activity, running away, or being out past curfew. While these might warrant attention from law enforcement, they do not directly address the immediate concern of the minor's safety. The correct determination lies in assessing the risk factors that threaten the minor's well-being, which is foundational for justified intervention without a warrant.
