With the South African police's dismissal of the lead investigator presenting a new twist in the case of Paralympic sprinter Oscar Pistorius, on Wednesday evening Piers Morgan invited Kim Martin to offer personal perspective and unique insight on a story that has captivated people across the globe.

A cousin of Reeva Steenkamp, the model girlfriend shot dead by Pistorius on Valentine's Day, Martin spoke of the "surreal" moment of learning the news while stuck in traffic and listening to the radio:

"I just remember thinking the whole time that there's no way," said Martin. "This is not - somebody is playing a joke, and they're going to - the radio guy is going to come on and say that this is a big joke."

Continuing to express disbelief, the guest simply could not accept the passing of her cousin:

"Reeva is not supposed to be dead. Reeva had her whole life ahead of her. She was going to be doing great things."

Also as part of last night's "Piers Morgan Tonight" program, the host continued the gun conversation, welcoming Paxton Quigley who spoke specifically about firearms being used by women.

The author of "Armed and Female, Taking Control," Quigley addressed gun manufacturer marketing campaigns that are geared to a female audience, and the ways in which such advertising impact sales:

"I think they're [gun manufacturers] marketing that way, but I don't think women are following in that way," she told the host. FULL POST

On Thursday evening, author, journalist and television news producer Lisa Cohen joined "Piers Morgan Tonight," offering her unique insight into the latest news in the Etan Patz case.

Nearly 33 years to the day since the 6-year-old boy went missing, yesterday 51-year-old Pedro Hernandez was arrested in Patz's death. The former Manhattan store clerk lived in the family's neighborhood when the boy went missing. Having literally written the book on the Patz case, Cohen called the latest development "extraordinary," noting that she had "never heard of this man before today."

Also on Thursday, comedienne, actress and author Ali Wentworth visited Morgan for an in-studio face to face interview. The host of Yahoo.com's "The Daily Shot," Wentworth's three to five minute web series is geared towards busy moms who need a quick "shot" of news in a hurry.

Discussing the current state of America politics, Wentworth wasn't above taking things below the belt: FULL POST

Guns N' Roses and Rock and Roll Hall of Fame guitarist Slash joined Piers Morgan on Wednesday for a primetime exclusive interview. The legendary musician talked with Piers about his music, his battle with drug addiction and his iconic style.

In 1996, at the pinnacle of their success, Slash left Guns N' Roses and ended his friendship with lead singer Axl Rose. Recalling their last verbal exchange, Slash said, "I think the last word, basically it was just that 'I'm done.'" When asked by Piers if there was a possibility for the band to reunite, Slash responded, "I don't think it's a matter of that, it really isn't."

"I think you've got a situation where nobody involved wants to revisit - it's not just me," said Slash, "It's the whole, you know, the whole band. And so I don't think there's a price tag that anybody's going to put in front of us that's going to make that work, you know?"

Also on Wednesday, business executive, author and Mitt Romney supporter, Jack Welch joined Morgan for a quick sit down. On topic was Romney's strategy to present his work at Bain Capital as an example of job creation. FULL POST
