The talk show host and former prosecutor brought up two issues throughout the broadcast: why do investigators think Hailey is alive and what sort of inconsistencies have the key players in the investigation been making?
During the broadcast, KTAB's Priscilla Luong answered the first issue by delivering the breaking news that law enforcement now does not have enough evidence to believe Hailey is a runaway or in hiding.
Hailey's mother seemed to indicate this development was news to her.
"We were starting to get a little hopeful and now that hope is fading," said Billie Dunn.
Grace and her panel of guests said that by law enforcement reporting one day they were optimistic Hailey was alive and saying the next there's not enough evidence to support that ultimately harms the investigation.
Even so, Grace came to the defense of the authorities and their overall effort.
"At least they are trying everything; you have to give them that," said Grace.
On the issue of inconsistent statements, Grace asked Hailey's mother Billie exactly what was inconsistent about the statements she made to authorities.
"I don't know," said Dunn. "I asked one of the Rangers about that and he's supposed to be getting back to me."
Grace asked Dunn if she took drugs prior to her polygraph tests and if that might have caused the "inconsistencies."
After Dunn denied that claim, WOAI News Radio reporter Michael Board said investigators feel some of the witnesses may not be credible due to a history of drug use.
"I'm a credible witness," said an emotional Billie Dunn. "I'm not a liar."
During the broadcast, Board also reported that investigators believe Hailey may be hiding out of state - possibly in New Mexico or Arizona. Board went on to present a theory that she could have hitched a ride with an 18-wheeler or a friend with a driver's license.
Grace responded with frustration essentially saying that Board's theory was rumor rather than fact.
