Sec. 4. A rebuttable presumption is raised that the child is a child in need of services because of an act or omission of the child's parent, guardian, or custodian if the state introduces competent evidence of probative value that:
(1) the child has been injured;
(2) at the time the child was injured, the parent, guardian, or custodian:
(A) had the care, custody, or control of the child; or
(B) had legal responsibility for the care, custody, or control of the child;
(3) the injury would not ordinarily be sustained except for the act or omission of a parent, guardian, or custodian; and
(4) there is a reasonable probability that the injury was not accidental.
