Topics and Guests for July 23

We come to you LIVE from the heartland Saturdays at 8 p.m. ET!

Former Ohio congressman and host John Kasich covers the stories that touch our entire nation!

Here's what you'll find on our show this weekend:

As authorities conduct DNA tests on blonde hairs attached to a piece of duct tape found on a beach in Aruba, DNA samples are taken from jailed teen Joran van der Sloot (search) and the now-released Kalpoe brothers. What, if anything, will the results of the DNA tests reveal? We'll ask forensic pathologist Cyril Wecht.

Next, we'll get an update on the Natalee Holloway (search) investigation from Jossy Mansur, editor-in-chief of El Diario, Aruba's largest daily newspaper and Aruban attorney Arlene Ellis-Schipper.

And, the Holloway-Twitty family increases the reward for information in the disappearance of Natalee to $200,000. Will the increased amount bring people forward with crucial information? We'll talk with Natalee's mom, Beth Holloway Twitty.

Exactly two weeks to the day that four deadly bombings killed 56 people in London, another less-deadly attack rocks the city. Is London mayor Ken Livingston (search) soft on terror? British journalist Christopher Hitchens and John Loftus, former intelligence officer and president of the Intelligence Summit, weigh in.

Then, the Broward County Sheriff's Office (search) left one word off a Miranda rights form and now at least 25 cases against suspected killers, robbers and drug dealers are compromised. The mistake could result in overturned convictions, dismissed charges and weakened cases for prosecutors. So how did this happen?! We'll ask Pat Campbell, Florida radio talk show host.

Plus, a painting of an American flag being flushed down a toilet is causing quite a controversy. So is it offensive artwork or freedom of expression? We'll talk with the man behind the painting, Stephen Pearcy.

Those stories and more on this Saturday's "Heartland."

Be sure to watch "Heartland" this Saturday evening at 8 p.m. ET and on Sunday at 4 a.m. ET.
