(a) A law enforcement officer who, during a criminal investigation relating to a child's custody, discovers that a child is a missing child and believes that a person may flee with or conceal the child shall take possession of the child and provide for the delivery of the child as provided by Subsection (b).
(b) An officer who takes possession of a child under Subsection (a) shall deliver or arrange for the delivery of the child to a person entitled to possession of the child.
(c) If a person entitled to possession of the child is not immediately available to take possession of the child, the law enforcement officer shall deliver the child to the Department of Family and Protective Services. Until a person entitled to possession of the child takes possession of the child, the department may, without a court order, retain possession of the child not longer than five days after the date the child is delivered to the department. While the department retains possession of a child under this subsection, the department may place the child in foster care. If a parent or other person entitled to possession of the child does not take possession of the child before the sixth day after the date the child is delivered to the department, the department shall proceed under this chapter as if the law enforcement officer took possession of the child under Section 262.104.
