(1)    Taking child into custody. In addition to being taken into custody under s. 48.19, a child whom a law enforcement officer, emergency medical services practitioner, as defined in s. 256.01 (5), or hospital staff member reasonably believes to be 72 hours old or younger may be taken into custody under circumstances in which a parent of the child relinquishes custody of the child to the law enforcement officer, emergency medical services practitioner, or hospital staff member and does not express an intent to return for the child. If a parent who wishes to relinquish custody of his or her child under this subsection is unable to travel to a sheriff’s office, police station, fire station, hospital, or other place where a law enforcement officer, emergency medical services practitioner, or hospital staff member is located, the parent may dial the telephone number “911” or, in an area in which the telephone number “911” is not available, the number for an emergency medical service provider, and the person receiving the call shall dispatch a law enforcement officer or emergency medical services practitioner to meet the parent and take the child into custody. A law enforcement officer, emergency medical services practitioner, or hospital staff member who takes a child into custody under this subsection shall take any action necessary to protect the health and safety of the child, shall, within 24 hours after taking the child into custody, deliver the child to the intake worker under s. 48.20, and shall, within 5 days after taking the child into custody, file a birth record for the child under s. 69.14 (3).

      (c)    No officer, employee, or agent of this state or of a political subdivision of this state may attempt to locate or ascertain the identity of a parent who relinquishes custody of a child under sub.

   (3)   Information for parent.

      (a)    Subject to par. (b), a law enforcement officer, emergency medical services practitioner, as defined in s. 256.01 (5), or hospital staff member who takes a child into custody under sub. (1) shall make available to the parent who relinquishes custody of the child the maternal and child health toll-free telephone number maintained by the department under 42 U.S. Code § 705 (a) (5) (E).

      (b)    The decision whether to accept the information made available under par. (a) is entirely voluntary on the part of the parent. No person may induce or coerce or attempt to induce or coerce any parent into accepting that information.

   (4)   Immunity from liability.

      (b)    Any law enforcement officer, emergency medical services practitioner, as defined in s. 256.01 (5), or hospital staff member who takes a child into custody under sub.

In promulgating those rules, the department shall consider the different circumstances under which a parent might relinquish custody of a child under sub. (1). The rules shall include rules prescribing a means by which a parent who relinquishes custody of his or her child under sub. (1) may, until the granting of an order terminating parental rights, choose to be identified as the child’s parent.
