(CBS News) Trayvon Martin's parents rejected on "CBS This Morning" Thursday George Zimmerman's reasoning that shooting the Florida teenager to death last February was "God's plan."

The neighborhood watch volunteer accused of second-degree murder appeared on Fox News Wednesday night and said he acted in self-defense when he shot Martin. He also apologized to Martin's parents.

"I simply really don't know what god George Zimmerman's worshipping because there's no way that the god that I serve had in his plans for George Zimmerman to murder my son," Martin's father Tracy Martin told Norah O'Donnell.
