Justin took the test under "very controlled circumstances" and there was a solid chain of custody, making the DNA test virtually unchallengeable by Mariah Yeater and her lawyer. Now it's up to Yeater to complete the DNA testing by submitting a sample from her child.

What do you think? Is Justin the father of Mariah Yeater's baby?
